Visual artifacts when HDR enabled at 175Hz
bug
Hi all, new to Bazzite and Linux in general. Having trouble with this and haven't seen any other information online so figured I'd ask here.
I'm using the nvidia-open desktop KDE build using an RTX 4080 Super powering a dual monitor setup, my primary 3440x1440 175Hz Samsung Odyssey OLED G8 HDR ultrawide monitor and a secondary basic 1440p 60Hz LCD monitor. For the primary monitor, I use a HDMI to mini-HDMI cable specifically to enable HDR10+ in Windows which works in a few games I play.
The issue I have is that when I run the primary monitor at 175Hz and enable HDR, small white artifacts begin to appear at random every few seconds, which last for maybe a fraction of second at most, but they are enough to notice and be rather annoying. This happens no matter the content being displayed, even a static desktop will show this issue.
If I disable HDR, this issue does not occur. If I reduce the monitor refresh rate down to 120Hz, I can then enable HDR without issue. I have enabled VRR on all these scenarios - yet to test with it off. The secondary display works fine.
This makes me think it's a limitation of the current nvidia driver, but I'm hoping someone else out there running a similar setup has had these issues and if they have any fixes for it - I have no major issues with my current workarounds but ideally I'd like to match my Windows setup which can achieve 175Hz HDR without trouble. Thanks in advance!
