Parts of my GUI are flickering on Fedora KDE

It is very odd. It is ONLY the right half of my monitor. My resolution is set to the native resolution of 5120 x 2160. My refresh rate is native at 165.06hz, and adaptive sync is set to “never.” I’m running an Nvidia 4070Ti, and modinfo -F version nvidia outputs 610.57.04.

I’ve tried switching the adaptive sync to all three different modes, as that was what some people online suggested. But I am running out of ideas to troubleshoot this issue. It does not happen on Windows. Does anyone have suggestions on what to attempt next to fix this?

What version of the kernel do you have?

uname -r outputs 7.1.7-200.fc44.x86_64

That could be the problem; 7.1.6 and 7.1.7 are known to have a similar-sounding bug. Supposedly 7.1.8 fixes it.

That issue is amdgpu specific, the OP has nvidia gpu.

Does booting from a previous kernel make a difference?

why does nobody ever check this?

according to the nvidia website, you should be using the 595.91.07 driver … not just the one with the highest version number.

try that.

@skyfishgoo
No problem with 610.57.04 on a 4070M here or the 610.x series so far.
But my highest single Monitor resolution is 3840 x 2160 at 120 Hz, that could play a role, and the Nvidia GPU is mostly used in Games (not much of the KDE GUI to see there :sweat_smile: ).

595.91.07 could be worth a try a least.

Does nvidia say why you would not used the latest drivers?

yes they say that is the recommended driver because

This driver meets the quality levels applied to Windows

:rofl:
and the newer one is for early adopters and bleeding edge developers (only)

no, they just say which drivers to use with which GPU.

i would imagine the latest drivers are for their latest GPU.

a 4070 is far from their latest model.

The 610.57.04 drivers are what RPM Fusion provides, so it’s the version that most Fedora users are on.

I feel like we’d have had more reports on the Fedora forum if there was a wide-scope bug here.

Not impossible that there’s something that only reveals itself when you really push the bandwidth though - that’s a demanding resolution and refresh rate.

It’s explicitly supported by this version, as are a few previous generations (Supported Products list here.)

is it the ONLY one they provide?

advantage kubuntu

out of curiosity what version of linux-firmware are you using and did it recently just get updated?

That, or the original one that was provided for the release - i.e. 595.58.03 in the case of Fedora 44.

That’s great news! Unfortunately, I ran a dnf upgrade, and it did not update my kernel. I also tried dnf update kernel, and still had no luck. Is there something I’m missing?

Yeah, I was on the fence about Kubuntu or Fedora…ended up with Fedora, and already starting to regret it. :confused:
