I’m running Manjaro Plasma unstable here with kernel 6.12.4-1-MANJARO currently, and I ran into this with my Framework 16 iGPU (I don’t yet have the dGPU). I couldn’t use adaptive sync at all, or the display would freeze constantly. I read the bug linked here, and I tried what this post suggested and added amdgpu.dcdebugmask=0x400 to my kernel parameters. Now I’m able to use adaptive sync in display settings, as well as play Trackmania in full screen mode.
