Title:
amdgpu: [gfxhub] page fault when switching a video to or from
fullscreen
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi,
Switching a video to or from fullscreen freezes the screen for around
10 seconds. This happens with Totem as well as VLC so its not related
to a specific app.
Additional observations:
- The issue seems to be connected to the video's bitrate. With low
bitrate videos I cannot trigger the freeze. However, videos with high
bandwidth trigger the freeze reliably.
Specs:
Ubuntu 23.10 up to date as of 28.09.2023
AMD Ryzen 7 PRO 6850U
Kernel 6.5.0-5-generic
Grub configured with: amdgpu.vm_update_mode=3
