Hi @thesword53
I forced EDID into my display but could not duplicate flickering and artifact issue.as shared in video in this thread.
Hi @thewisenoob
Request you to please check once with 580 beta release driver.
Hello @amrits. I don’t have flickering or artifact issues. My monitor completely loses video signal when I am using VRR. It happens for example when I set Adaptive Sync to “Always” in KDE settings after a couple of seconds or briefly when I quit or unfocuse a program using VRR. It only happens when at 360Hz.
with 580.65.06 flickering still happens
specs, 5950x 4090, display port, happens only on the right side of the monitor, tried it with second monitor and the moment i increase the hz above 144 with 4k it starts happening
Here is also video, but it shows similar symptoms but not the same, so if it’s not related to this ticket, i can create a second one
This is not application specifies just this was the most repeatable ish way i found i can replicate this
as stated the glitch never happens on the left size of screen, as if it’s splitting the monitor as 2 4/2k screens rotated horizontally
Interesting is it happens right when dsc should be active, but what makes me thing it’s not dsc is it should not have context of what happened 5 mins ago, since in the video i fullscreen a browser window, and i will be able to see desktop, or if another app is bellow it, it would see it
not browser specific, i can make it happen when running k9s in alacrity
Hi All,
I can see flickering on my test system running KDE Plasma on Wayland only on right bottom side of the screen when I set resolution and refresh rate as 5120 x 1440 and 240 Hz respectively connected via DP connection.
Further I observed similar flickering using 4k + 244 Hz when HDR option is enabled.
Engineering team will investigate this issue and shall share feedback once it’s available.
Attaching video for the reference.

glad you could repro
it’s the same bug as DisplayPort DSC 4K@240Hz flickering artifacts - #34 by PcChip I believe

Is there any update?
I also have the same issue on 4K@240hz. No issues on 4K@120hz, so it might have something to do with DSC.
@rrameshbabu Hi again, I believe this is related to the topic we spoked about on GitHub. I will ping in the other thread as well since I believe they are related.
FYI @amrits this still happens even on 590 beta
same with 580.119.02
This person said this environment varriable fixed his flickering in the 590 driver thread,
https://forums.developer.nvidia.com/t/590-release-feedback-discussion/353310/107?u=tda0626
For giggles, maybe someone give it try by adding it to their environment config?
if what you mean by that is the VK_ICD_FILENAMES, then no, i have that set and no difference, don’t think we are talking about the same type of flicker
example:
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 :
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 bug for sure.
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 is a MSI MPG321URX-QD OLED which is connected via display port directly to the monitor. People affected must have something in common it’s just a question of finding what. I’m using a high quality DP cables supporting 8K60hz. Again it might be something else. I might be related to adaptive sync. My monitor has it enabled but the KDE settings for it is disabled inside the OS. People seems to think it’s related to Display Stream Compression but that just a theory.
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 the same half, downgrading a monitor to 144hz removes the artifacts completely for the select screen
edit: i can replicate it on kwin and whatever gnome uses
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 the drivers anyway as Windows work perfectly fine.
