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.

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 
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.
6.14RC1-1 is working well so far
FYI 6.13.1 contains the fix too.
yup, just tried it, and it also seems to work fine too. Thanks!
Sorry it’s not working. I have the same effect with Kernel 6.13.2-2
Update:
All is fine when i use Cachyos Browser but it change when…i use Edge (installed with flatpak) look at full screen youtbe Video the same effect (flashing black). When i change now to Cachyos Browser youtube full Screen same effect (flashing black)
