I’ve been testing a multi-monitor DisplayLink setup on Windows 11 24H2 with a USB4 dock, and I keep noticing random cursor lag, delayed window rendering, and occasional monitor refresh stutter after waking from Modern Standby.

I already tested:

latest DisplayLink drivers
different USB4 cables
disabling Hardware Accelerated GPU Scheduling
HDR on/off
mixed refresh rates

The strange part is that everything works perfectly after a fresh reboot, but performance slowly degrades after sleep/wake cycles.

Could this be related to GPU scheduling conflicts between DisplayLink and newer Windows power management behavior? Curious if anyone else using Intel Core Ultra or Ryzen AI laptops has seen similar issues.
