I updated Arch and now I can’t use my screen above 60fps when using 4k without horrible artifacts and the screen regularly going black for a second or two. 60fps is stable. I can downgrade using timeshift, but I’d prefer to not have to because I really want to start using Wayland full-time. Right no…

It looks like it was after hunting down his video in the 580 thread.

The flickering happens only in the right half bottom corner of the screen. Something seems to be fighting to render in the proper order. If you have applications running like game you can see through and see the desktop. You can see my original videos here : https://forums.developer.nvidia.com/t/di…

[image] hyrules: It’s odd that nvidia has issues reproducing. This happens to a lot of people here on the forums. Right but I can see that happening because I am not affected by this bug for some reason and I have an Asus PG32UCDM 4K/240hz monitor. It stays in 240hz mode all the time. Odd bu…

There are a lot of factors that could cause this. Personally i’m on arch linux Endeavour OS. It could be an issue with having multiple monitor with different refresh rate. I have 3 different monitors. 2x 144hz (one running at 120 because of AVR audio) and 1 running at 240hz. My main monitor on 240hz…

And for me it’s 4k240hz and 4k160hz, the artifacts seem to grow higher the higher the refresh rate is, given the video above, that same animation amount on 240hz it grows as you can see till 25% of the half of the screen, while if i replicate it on the 160, it’s barely visible at 5-10 ish percent of…

Have you tried it with just monitor connected to test to see if it might be multimonitor related? Forgive me if you have.

Not at the moment. I need at least 2 because of audio. If my AVR is not connected through HDMI I don’t get any audio. My guess is it might be related to that as most post i’ve seen people seems to have multiple monitor setup. Even if this is the issue that means that there is something wrong with th…

@tda0626 if i unplug the monitor psychically or disable it via software issue is gone, no clue how i missed this, this would also explain why issue is not as prevalent sorry for ping but this may be important @amrits @vrachatte @amrits , i assume the video you took in the post above was with a mu…

My earlier flickering (local repro) turned out to be another bug, apologies for the same. We are currently trying repro with multiple display combination for flickering and artifact as posted in earlier videos. Hi @hyrules @borna.vincek1 Would you be able to share edid of affected displays.
