This is probably a less than stellar thing to test with you running KDE but try disabling the compositor (KWin). I’ve been running a while without my compositor and the flickering seems to be gone. I’ll be interested if this fixes things for you too. Then at least we’ll have an idea as to what the driver is causing issues with.
I unchecked the compositor (enabled on startup = off) and i think its reduced alot, but i saw it flashing again 2 time in the last 10min, im not sure if its a placebo but it looks less frequently now… but still there.
Maybe a restart is required for fully disable after i deactivate the check box… im not deactivated the service Kwin yet or should i try that next?
Like dvsaleios said, it has nothing to do with compositor… i tested it out and i could see it flickering with compositor disabled, it may reduce a little because the powerstates not switching and jumping around as with compositor enabled but no real difference.
I swapped PowerMizer to ‘Prefer Maximum Performance’ in nvidia-settings. That mitigated it. Still happens but with a lot less frequency. I don’t know how the curve looks with that profile but it will sometimes go down to 2 from 4 every now and then.
Yeah, I’m hoping an NVIDIA engineer can clarify the proper issue at some point.
Changing power states does not trigger it for me. There is no doubt it’s a driver bug, I never said the bug was the compositors but merely the flickering was the driver bug tripping up the compositor. If we can be free of the obnoxious flicker by shutting down the compositor for a few days until this is fixed then it’s a better alternative.
I am running sans compositor and I have not seen the flicker. That said the driver bug is probably affecting various draw calls my machine doesn’t do but yours does due to running KDE. All the KDE effects and features will no doubt use various calls and transforms on the GPU that will trigger the problem far more than my WM.
For me it happens at any time. Working in Blender, Unity, playing Tarkov. I’ve looked at a few other bugs that got put into mainline and looks like if anyone checks my logs it will be at least a week or three before someone that can fix things will even notice.
I also see it alot when i work in Shotcut to Edit some Video files… when i hovering about the menue and the overlay shows up and so on… maybe it is related to powerstates, but not only… atleast thats what i guess.
You talking about that flashes in Tarkov when you in a menue or when you actual playing and running around?
I see it alot flashing when i playing Beyond all Reason and when im inside the lobby (2D) but on the 3D environment, there is everything fine… or i might just dont saw it yet.
It happens at any time. Like I said in my original post there is no workload or “thing” that triggers it more or less. I can be in menus, playing, working, coding, doesn’t matter. There doesn’t seem to be a timed cadence/interval either.
Given killing picom seems to have quelled it it makes me think there are some draw calls the new driver does that trips various things up. Just so happens on my machine picom is the most affected. That said I also never get anything in the syslogs or any other log about errors or issues when it happens. Just there then gone until the next time with seemingly no indication anything happened other than I saw it.
