Hello, I have short flickering at the top of the screen. I have noticed this issues starting from driver 530.41.3. It is still present in driver 535.43.02. Setting nvidia_drm.modeset=1 doesn’t work. I don’t have this issue with driver 525.116.04. I have a RTX 2060 Super. EDIT: I have found out ...
I know NVIDIA on Linux is somewhat bad, but this bug has been driving me insane, and it is still not fix as of 535.104.05 my screen flicker even more than the last driver update
I hope this get fix in 540 drivers updates or later, but I'm getting an AMD GPU when I get to build my PC very soon.
Oh my goodness, I'm sorry to hear that this is happening to others but I am so glad its not just me. This has been something that's driving me crazy, because I knew it wasn't a cable / GPU issue due to the fact that it doesn't occur in Windows.
Whether I use Wayland or X11, I just get random flickers at the top - doesn't seem to be caused by any specific application either, nor is it isolated to any specific DE (I've gotten it on both GNOME and KDE).
I'm on an RTX 2080, with driver version 535.98 - I'd love to just "use an AMD card" but short of one just falling out of the skies right into my hands, that's not going to be happening anytime soon sadly.
Edit: From OP's link to Nvidia's forums, someone did mention that setting the GPU's power mode to Performance somewhat mitigates the issue. This can be set by opening the Nvidia X Server Settings app (or sudo nvidia-settings) and under your GPU -> PowerMizer -> Preferred Mode. I've just set this now, I guess we'll see how that goes - but do expect power usage to probably go up by doing this.
My monitor is only capable of 1080p, so it just always runs at 1920x1080 - I haven't tried lowering the resolution yet to see if that has any impact, but I suspect it won't sadly.
I've been waiting on this issue the day it was posted... It doesn't bother me as much as I have a second vertical monitor so the flashing is at the edge of the vertical one, and it's definitely reduced but not gone away. Coupled with these recent driver updates, my X server just gets slower over time (not in game, thankfully).
Nvidia doesn't even have to go FOSS, they can just go OS, and this issue could probably be resolved by now due to increased transparency of what the f is going on with the drivers, as well as better collaboration between kernel developers and driver developers. Who knows what they're attempting behind the curtains, 3+ releases since this bug was filed and still not fixed.
I had it come back after the 535 drivers dropped for my 1660 super. Was lucky that downgrading back the previous version took it away.
From what I read it introduced the flickering for a bunch of other cards too.
It got fixed in the windows driver for the 1660 freakin ages ago but only recently on Linux before the reintroduced the issue recently. Changing the power mode never did anything for me.
I had the same situation and solution with my 1660ti. I thought there was something wrong with my monitor for a bit because it didn't show up on the second screen.
