UI sometimes freezes for 20-30 seconds while playing video in firefox or smplayer. Only mouse pointer can move around without being able to click anything.
I couldn’t find out exactly how to reproduce the error. I have checked intel_gpu_top, error can happen both using hardware acceleration or not using.
