--- Comment #74 from MirceaKitsune sonichedgehog_hyperblast00@yahoo.com --- pcie_aspm=off makes no difference. In addition, I tried booting back to the radeon module (instead of amdgpu) and disabling the SI scheduler: This seems to have slightly mitigated the problem in some cases (eg: Blender) but made no difference in others (eg: Xonotic).

As for suspending to RAM: I haven't used Standby mode in ages. I never suspend my computer to RAM, so this could not be an issue.
