Bug report: grainy edit viewer video

Version DaVinci_Resolve_Studio_17.0b6_Windows

See screen snip. My problem (chicken soup) project used 24fps and 30fps clips in a 24fps 1080HD timeline. After rendering, the cut and edit viewer video became unusable - blue/green and grainy - all clips; not just the 24fps or just the 30fps. Source viewer was fine. Color and fusion pages also fine.

In one quick experiment, I added a 30fps clip to a previous 24fps project and rendered it. This duplicated the problem. After deleting the single 30 fps clip, the edit viewer video displayed correctly again. Unfortunately that didn’t work on my chicken soup project.

Next workaround. I exported the timeline and imported it into a new project using a 30fps timeline. I rendered a clip and the corrupt screen appeared momentarily then went back to normal without intervention. Fingers crossed.

AMD GPU?

AMD GPU?

NVIDIA

I'm using three EVGA GeForce GTX 980 cards in SLI configured to "maximize 3d performance"

Alright.

First check this.

BLUF: Updated my GPU driver. No effect.

Of course my NVIDIA driver was ancient - in my experience, updating only ever seems to CAUSE problems.

That said, "Studio" version of NVIDIA driver 460.89 refused to install so the best I could do was a file listed as a "Game ready" - file name: 460.89-desktop-win10-64bit-international-dch-whql.

The original problem persists, but my workaround is also holding fast.

OK.

My next recommendation is to undo the SLI. (It's not recommended for Resolve.)

It seems SLI was the problem. Thank you.
