6.13 kernal screen flashing black

Since 6.13 hit, my screen starts flashing black when I move the mouse, or type in terminal or any text field. When I stop, the screen comes back, and I can see what I typed did show up. I managed to get back to 6.12.10-1 lts through the screen flashing, and it works again.

9800X3D CPU, 870E MB, 7900GRE GPU. KDE DE

I’m very new to Linux. I just switched in December and am still trying to learn what I can.

Does linux-cachyos-rc have the same symptoms?

yes, looks like any of the options for 6.13 do it. going back to 6.12 immediately fixes it.

With 6.13 I am experiencing heavy flickering when in fullscreen.

7800XT here

Please install the 6.13 rc kernels from here CachyOS - Repo. 6.13rc1 and 6.13rc4 are available. There seems to be something not well baked that got in 6.13.

Thats sad :slight_smile:

You can install the LTS kernel, which is now on 6.12.10:
sudo pacman -S linux-cachyos-lts linux-cachyos-lts-headers

We are trying to work together with AMD to fix this issue asap.
