@PaulNi2 What are the system version and OS build version? Could you provide a video of the issue occurring (showing the operation process) so that we can better understand the problem? Sorry for any inconvenience it may be caused.
Linux 6.12.8 Windows 11 latest, though replicating it under Windows is much harder. You want to set maximum powersave settings, and then run something GPU intensive with variable refresh rate
