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

Syslog shows:

2023-09-28T20:02:29.803955+02:00 kernel: [27003.800898] amdgpu 0000:04:00.0: amdgpu: [gfxhub] page fault (src_id:0 ring:24 vmid:2 pasid:32771, for process Xwayland pid 2113 thread Xwayland:cs0 pid 2311)

Cannot deliver additional logs at the moment, though I think they might not be necessary. Setting the bug to confirmed as stated by the Kernel Bot.

In this case the kernel is the "messenger" for the page fault. This is more likely to be a mesa or application issue than a kernel issue.

Can you please raise a ticket to the upstream mesa bug tracker?

Also - can you still repro with mesa 23.2.1-1ubuntu2? This just landed right after you reported this issue.

Yes, it still happens with mesa 23.2.1-1ubuntu2. Additionally, it is not only with video fullscreen. Same happens if I start synaptic for example. Sometimes it hangs for 10 seconds too. Seems to affect multiple applications and is triggered by multiple ways.
