Bug: Fusion Studio 20.2.2 crashes when OFX plugins are used

It would appear that todays release of Fusion Studio 20.2.2 has broken OFX plugins. I use Frischluft depth of field (a common paid for OFX plug-in that makes up for the lack of a good depth of field simulator in Fusion) and a number of other plug-ins that Frischluft offer for free on their website, although the depth of field plug-in is the only really essential one. This has worked for years and is used by a number of other fusion artists.

When I load Fusion Studio 20.2.2 I get a group of error windows that says Fusion has failed to load these plugins. If I press OK on the dialogue a number of times to clear the error dialogue windows Fusion appears to be working, but if I try and load the frischluft depth of field plug Fusion instantly crashes.

TO DEMONSTRATE - load Fusion Studio 20.2.2, press OK a number of times to clear error dialogues, try and load frischluft depth of field OFX plugin.

RESULT - Fusion crashes immediately

win 11 pro, Nvidia driver 581.29

Hi,

Before installing, it was the right call to check here just in case. I'll check it on my MacBook later.

Thank you.

Further investigation on the WSL forum seems to indicate that the OFX error varies from system to system, with some systems running the plugin fine, others throwing a console error message and one of my own systems crashing fusion whenever the plugin is loaded.

Results are ongoing -

I'll report here if/when any conclusions are reached.

Hey

I posted there to know if specific OFXes which really don't work are spotted or not, which could help others. Seeing "and 6 others" is particularly bad so far...

I have been removing OFX plugins one by one and I can now see which ones are there - now there are only three, the frisch depth of field, Neat Video and Mocha Pro. Bizarrely although it says they're not loaded both Neat Video and Mocha Pro seem to work ok. But when I add a depth of field node fusion crashes right away. But only on the laptop machine.

I re-installed 20.2.1 and confirmed that everything loads and works fine on that even on the laptop. I removed 20.2.2 and fully re-installed again and it still crashes on loading the depth of field. I'm at a bit of a loss as how to debug this further.

Interesting that behavior differs across systems — makes me think it’s a compatibility issue with specific GPU drivers or the new OFX bridge in 20.2.2. Has anyone tried rolling back Nvidia drivers to see if that stabilizes it?

Given that all the plugins load with no problems on Fusion Studio 20.2.1 but throw up a not loaded flag and a crash when depth of field node is added on 20.2.2 on the laptop, both on the same graphics driver, paths etc. it would seem unlikely that the driver is the cause - more that there has been some change in how Fusion handles OFX from 20.2.1 to 20.2.2. But I agree, the fact that the plugins run fine on other systems and throw up an error message on another seems very odd.


Also, I've just update the driver from 581.29 to 581.57 with no change in behaviour. I will however try downgrading the graphics driver when I get a chance just to make sure.

…or the new OFX bridge in 20.2.2

What’s the new ofx bridge?

I've now tried this with some older graphics drivers and same behaviour. I then installed Resolve Studio 20.2.2 and tried it on the fusion page - the frisch depth of field node loads without crashing Resolve, and seems to work but has its own bug - the cursor that frisch throws up when node is selected and viewed isn't showing. As this cursor is used to pick the zdepth from the image this is a pain, but you can enter the x and y pixel co-ordinates into the node manually as a workaround. This same bug appeared some time ago in Fusion Studio but was fixed by BM devs in subsequent versions.

So - where we're at. The frisch OFX node loads and works fine in FuStudio 20.2.1. In FuStudio 20.2.2 loading errors are thrown up for OFX plugins and inserting a frisch depth of field node completely crashes fusion, but only on my laptop system (spec on laptop listed below). On my other systems there is no OFX load error and frisch works fine, although SecondMan reports a console error thrown on his system in a post above - "Warning: OFS Plugin Depth of Field reportw thread safety of OfxImageEffectRenderUnsafe. This is not supported in Fusion, and use of this plugin may result in instability".

So I'm at a bit of a standstill, unless someone from BM dev can have a look at this, I'm afraid.

Laptop (system that frisch plugin crashes fusion on) spec -

win 11 pro 64 bit
Intel Core i7 11800H
64 Gig RAM
Tong Fang motherboard GM7TN8P (U3E1) Tiger Lake-H
Nvidia GeForce RTX 3080 driver 581.57

Just tested on FuStudio 20.2.3 - exactly the same behaviour on the error machine as above. In this thread it appears I'm not the only one experiencing this.

No response from BM at all. It seems clear that something has changed in the way OFX is handled - can we please get some sort of response?

Thanks.
