Local files are not working better. I saw you tagged it regression as regression but since I have this system I don't think I saw this working properly.
I know it also affected Ubuntu 20.04 after I upgraded from 19.10 as stated at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574130?comments=all I don't think I tested on earlier Ubuntu versions, but I just booted debian-10 (installed from current i386 packages) to make a quick test on earlier kernel (4.19.0-11-686) and display is not breaking (but accelerated according to logs).

As suggested on other (obsolete) bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574130?comments=all I thought it was a VLC bug but actually it's also replicated using mpv: Just run mpv https://conf.tube/download/videos/ea60f030-90c1-4e8e-9782-bef14dd3b1d1-1080.mp4 It appears to work as expected Stop with Esc and run again Process will be stuck on creating window frame and then once windows is starting to show the video, desktop's frame buffer will become garbage: video's first frame looks like blicking in this triangle mess. system is still usable, audio is still playing.
