Dear Blackmagic Support Team,
the Linux version behaves very strange when it comes to UI bugs, GPU scopes and performance.
a) Black timeline: when switching from Color to Edit, we often find various elements of the edit page completely blacked out. This occurs faster on longform content, but pretty much happens instantly on some projects. A reboot of the software is required.
b) Color node labels are often destroyed aswell when switching between workspaces for Color and Edit. This happens pretty much instantly when switching for one single time from Color to Edit and vice versa.
Also the performance coupled together with the use of the GPU scopes is not usable at all. When using GPU scopes, we barely get 10-11 fps, when deactivating GPU scopes we instantely get fluid playback on the color page. The Nvidia driver only shows 25% use of VRAM both with GPU scopes enabled or disabled.
We run Resolve 16.2.8/17 Build 39 on CentOS 7.8 with 3x 2080Tis and 1x K4000 as a GUI card. Nvidia driver version is 460.56. Studio version, Decklink 8K Pro running Desktop Video 11.7. Another machine without a Decklink Card and 3x 1080Tis shows the exact same behaviour. Studio version with Dongle. Both in a shared DB environment and on local databases.
I've attached screenshots of the UI bugs to this thread.
