CSD bar becomes corrupted when switching betwen maximized and regular windowed modes

Open hazelnot opened this issue 2 years ago • 10 comments

Overview Description: CSD bar becomes corrupted when switching betwen maximized and regular windowed modes. Tends to at least partially disappear or fail to refresh, creating a hall of mirrors effect in the blank spaces.

Steps to Reproduce:

  1. Launch Celluloid
  2. Maximize the window 3 (optional). Restore the window

Actual Results: image image image

Expected Results: The CSD bar to resize normally

Version: 0.22

Additional Information: Running on Arch Linux, Gnome DE, installed from the Community repo

I can't reproduce this, but it looks like this could be a driver bug. I have seen something similar with other applications though (e.g. qemu).

Interesting. I also wanted to add that this doesn't happen when not currently displaying a video. Doesn't matter if it's actively playing or paused though.

I also tested with a music file, and it doesn't happen with the album art displayed either.

I have the same issue, but in my case even the menu popup becomes corrupted when navigating sub menus. Arch Linux, Celluloid 0.22. This could be related to GTK 4 GPU rendering since this doesn't happen on Linux Mint Celluloid 0.21

Same happens here. Arch, GNOME 42, GTK4 running on AMD RX 550 with AMDGPU driver. Video acceleration in mpv config set to auto-safe. VA-API mesa driver installed and configured.

Update: setting the GSK_RENDERER environment variable to cairo resolves CSD corruption, there's however still some corruption intact when toggling between window snapped and/or fullscreen states. Further, using cairo as renderer completely destroys CPU usage with a heavy framedrop penalty, it is no viable fix.

Update 2: Running both mpv and celluloid build from latest git main branch.

Update 3: ~~For the time being I changed my default video player to Clapper which utilizes GStreamer for video decoding and rendering instead of libmpv and doesn't experience these rendering glitches/faults.~~

Update 4: I spoke too soon. Clapper seems to have the same rendering woes that Celluloid experiences (screenshot below), while using a different stack entirely. Circling back to the mutter/GTK GPU rendering bug hypothesis @axel358 mentions.

Update 5: Running on X11.

Ah yeah, I want to also add that this only happens on X11, on Wayland it works fine

AMDGPU as well?

Yes

It seems that Clapper 0.5.1 no longer has this issue.

My system:

  • Arch Linux
  • gnome-shell 42.2
  • gtk4 4.6.4
  • mesa 22.1.0
  • AMD Radeon RX 6600
  • Xorg

I believe we should close this issue and bring it to gtk4 instead. This, in my case affects a lot of gtk4 applications not just Celluloid, mostly popup menus like Nautilus context menu etc

I am getting this bug on two computers.

  1. OC: Manjaro Gnome (Wayland), GPU: Intel HD Graphics 520
  2. OC: Manjaro Gnome (Wayland), GPU: NVIDIA GeForce MX150

Disabling client-side decorations solves this problem, but it's not a particularly pleasant solution.
