Screen Refresh Rate Problem After Update

[Aoden]

Last night, I performed the usual system updates, which included the 6.10 Kernel update. After restarting my computer, I noticed an issue with my screen: whenever an animation occurs, the screen momentarily turns black before returning to normal. If the animation is continuous, it appears as though the screen is constantly flickering between black and normal.

To troubleshoot, I lowered my screen’s refresh rate as a temporary solution. Normally, I run my monitor at 170 Hz on Xorg without any problems, but now I had to reduce it to 100 Hz. If I increase it above 100 Hz, the issue reappears.

For reference, my monitor model is the VX2780J-2K. Below, I’ve listed the packages that were updated yesterday in case it helps diagnose the problem:

Perhaps 6.10 has a bug or regression. Try temporarily switching to the LTS kernel to see if the issue persists.

See this thread (by me)…

Screen Flickering with kernel 6.10 and AMD noted

Just did my system update and have noticed the upper half of the screen flickering in both X11 and Wayland after updating to kernel 6.10. Problem went away when I reverted back to the 6.6_LTS kernel. I am finding similar reports searching the internet. My system is all AMD so, I don’t know if would effect nVidia or Intel. Just a heads-up and checking to see who else might be experiencing this. …and, of course, this is why I always say, “If you’re not just running with the LTS kernel, you sh…

LSS - seems to be associated with kernel 6.10 and disabling freesync on your monitor will alleviate the issue for now. Or, as was said earlier, just fall back to the LTS kernel and wait for the patch.

Despite the recent kernel update 6.10.1-zen1-1-zen, the bug still persists.

At the moment, I don’t see a problem with using my monitor with a constant 100 Hz, so I won’t switch to the LTS kernel. This way, I can check and report if the bug is resolved in the new kernel updates.
