Hi, I'm having the same kind of issue with a Ryzen 7 8845HS (afaik, almost identical to 7940HS). Would like to also direct attention to this upstream bug with Mesa 25.03 (current for Ubuntu): https://gitlab.freedesktop.org/mesa/mesa/-/issues/12809. Setting dcdebugmask=0x10 hasn't helped me, I'll report back if bumping up Mesa does.
