Davinci Resolve 17.4 UI Bugs

hi guys, i'm experiencing glitches and errors in the davinci interface apparently related to the scaling of some cursors on hover certain areas!

Can I check if your display scaling is set to 100% or 200%? Other scaling ratios can potentially cause issues with Resolve.

If you have integer scaling ratios, please add a note specifying the resolution and scaling ratio of each display and a link to your diagnostic logs.

Thanks

I have a very annoying bug in the color tab. I can't load the memory I save from other grades with the command CTRL + number ... I know it sounds crazy but it doesn't work, it used to work before I installed this last update. so annoying.

Hi, I discovered another user interface (UI) error in the COLOR PAGE TABLE ... after I came out of "full screen" my interface "changed some things".

I use a MBP 15" 2018 with an external usb-c monitor [macOS 12.0.1 (21A558) ] ... but in DR 17.3.2 i don't have this problem.

I have some print screens:

1. before full screen

I have also had UI scaling issues.

Since upgrading to a 4K screen a year ago, my process has been to set Windows scaling to 125% prior to loading Resolve Studio, which would cause the UI to scale at 100% on the 4K screen. I’d then set my windows scaling back to 150% for my other apps but this would keep Resolve in its 100% scaling which, although very hard to read at times, was the only workable option. Between that and 200%.

Now when I do this, the resolve UI rescales when Windows does and UI elements disappear in a bunch of places with clipping and cropped out areas, really not sure what’s going on.

Will it break anything if I rolled back to a 17.3.x to get the old behaviour? I’m an insane multitasker and tend to keep Resolve pen all day while I have other things I’m working on, but 125% scaling of my windows UI just doesn’t work for anything else.

Same here. I edit on a 4k screen and the only way I can use Resolve (studio version) is if I run the powershell script everytime I launch. I have it built into the windows shortcut (powershell.exe -WindowStyle Hidden "$Env:QT_DEVICE_PIXEL_RATIO=1;$Env:QT_AUTO_SCREEN_SCALE_FACTOR=2;start 'C:\Program Files\Blackmagic Design\DaVinci Resolve\Resolve.exe'")

This has worked like magic until this update. Now I'm back to a ridiculously-scaled unusable UI.

Blackmagic, PLEASE fix this. It's not feasible to set my windows scaling to 100% on my 4k monitor. It's also not feasible to edit on the UI the way it is. I don't care if it's too complicated to fix natively, just please re-enable the powershell hack.

For the record, I love Resolve. LOVE it! But stuff like this is a killer.

Research update: there's a potential (problematic) fix.

The original problem: Resolve UI scales terribly on a 4k monitor set at 150% scaling in Windows.

The clunky fix: set your 4k monitor scaling to 100% in Windows. This will make all of your programs way to tiny to work with.

The original classy fix: run a Powershell script when launching Resolve (build it into the shortcut) (see previous post for script). This will leave your windows scaling intact for everything else, but scale Resolve down to 100%. Some things are too small but you get used to it. The UI is no longer blurry and things are not over-sized. It's a decent fix. This broke with 17.4

The potential (problematic) fix: change your windows scaling from 150%, to a custom-set scaling of 149%. For some reason this will enable the powershell script to work again. Unfortunately, if you are running multiple monitors (I would assume most of us are) Windows will only apply a custom scaling to all monitors equally. If all your monitors are 4k, then you're potentially fine. However if (like me) 1 monitor is 4k and 2 monitors are 1440, then your 1440 monitors will also take on a custom scale of 149% rendering everything on those monitors over-sized and clunky, and potentially blurry depending on the program you're using.

Blackmagic Resolve Team: I love Resolve and I love what you guys do. I know these aren't easy fixes or they would be fixed already. Thanks for taking the time to help us overcome this.

For those that may be interested the roll-back to 17.3 was painless for me. It detected my database just fine and didn't cause any problems there. I didn't even have to reimport any of my titles, transitions, or VST presets.

Final update so far: the rollback turned out NOT to be painless. Video playback was laggy and having trouble getting up to the framerate for real-time playback. No idea why. It worked great before I updated to 17.4. Tried more uninstalling and reinstalling along with deleting Resolve system folders, etc. Got better but not all the way better.

Ended up doing a hardware switch and switching my 4k monitor over to my clean feed monitor so that I'm running Resolve on 2 1440 monitors. This enabled me to re-upgrade to 17.4 and forget about the scaling issue completely. I miss using the 4k monitor as my primary monitor but at this point I just need to move forward and make editing progress again. Playback still seems to lag a bit and take a second to get up to the full framerate speed but I'm hoping I'll get used to it and learn to ignore it.

Hi,

After i update Davinci Resolve to 17.4 version and now to 17.4.1 version, i have same UI Layout bugs ... if i use full screen preview (CMD+F) ... after i exit from full screen preview (CMD+F) ... DR UI LAYOUT it change things and position (I don't have this problem until 17.4 - 17.4.1 version).


[ MBP 15.1 / 15" 2018 + USB-C External Display 2560x1440 / macOS 12.0.1 (21A559) ]

You can see the difference UI when i use RESET UI LAYOUT.

Thank you and i hope somebody fix this. Cheers.

After installing 17.4 the Resolve interface (UI) became huge. This worked for me...

Right click This PC > Properties > Advanced system settings > Environment Variables > New. Add an environment variable to force correct value for your display.

QT_SCREEN_SCALE_FACTORS=2 (2 for 200% scale, 1.5 for 150%, etc.)

Now the UI is sized much better on my 8k monitor.

Following up on this.

I'm on Studio so I had (or have still maybe) a ticket with BMD on this. So far the only fix they have suggested is keeping my desktop below 150% scaling, which isn't really acceptable, or the high-DPI overrides in Windows which result in janky blurriness and still not the desired result. Custom scaling also doesn't work since the 2nd monitor is a 1080p and it ends up scaled ridiculously with a custom.

I have not heard anything from BMD since 11 November.

I've confirmed even with 17.4.2, the command line switch remains ineffectual.

To reiterate, my simple fix for all prior versions of Resolve 17 was simply to downscale to 125% for the one minute it took to launch Resolve, then revert to 150%, and this kept everythign scaled at 100% which although tiny, was way better than 200%.

BTW here viewtopic.php?f=21&t=151455 I reported some, hmm, unexpected behavior, too (which may also be an UI bug?)

Scaling is terrible in Resolve it's either the native 4k screen which takes a lot of getting used to with how tiny it is. Or the native 1080 screen which is just so squashed it's practically unusable, especially on smaller laptop screens

Yes, concur, and this has been known for a long time. But prior to 17.4, you could keep a 100% scaling for the Resolve UI with a different (and usable) scaling for your desktop. This is no longer possible since 17.4

Following up again on the scaling thing…

This is the response I finally got from BMD tech support:

“ Hello,
we anticipate no changes in this regard at this time. Most likely the result is the new QT library used for the interface. There were NO command-line switches inherent to Resolve, you were modifying something on the OS level.”

So, even the command line / power shell method isn’t supported and won’t work again unless someone figures out a new switch that will do it (force the UI into 100% scaling even if the desktop is scaled at 150 or more).

Huh? They are using a QuickTime library for the GUI on PC? Seriously?
Scaling is good on Mac, where QT originated.

Qt over here is not QuickTime, it's just Qt, which is a bog-standard implementation for cross-platform GUI in pretty much every professional app out there.

The difference being, that while pretty much every single app out there has implemented GUI scaling to accommodate for the hardware variety that Windows accommodates, Resolve stubbornly remains probably the only major app out there to have no implementation whatsoever except doubling in size. It's an embarrassing situation for Resolve, and it's been enough to push me back to Premiere for the meantime, because I can't use Resolve's clown superscaled interface on the monitors I own.

I refuse to put a gigantic 32+ inch monitor on my desk just because of Resolve's archaic inability to handle 4K resolutions like a modern app should. At 32 inches I lose all the crisp text and vector resolution that I upgraded to 4K for in the first place.
