Wayland freeze with libnvidia-egl-wayland1 package installed

[Gonzalo Garramuno]

My C++ application using FLTK on Wayland (a video player and review program):

https://www.github.com/ggarra13/mrv2

sometimes stops playback randomly.

The problem occurs with:

- Wayland (XWayland and X11 is fine)
- libndivia-egl-wayland1 installed for OpenGL acceleration (Mesa works fine but cannot play 4K)
- FLTK

It is not yet clear if the problem is with EGL or FLTK's use of it. The FLTK Wayland developer lacks an NVidia graphics card so he cannot troubleshoot it. I am hoping Ubuntu's developers or, if you have NVidia contacts, can verify whether it is a driver issue or an FLTK issue.

To quickly compile my application for testing, clone the repository and from the root of it, run:

mkdir -p ~/bin
./bin/runme_ffmpeg_exr.sh (for the most minimal player that should take 8 mins to compile)

A link to the .sh executable will be placed on ~/bin.

If you want to compile a debug build, run:

./bin/runme_ffmpeg_exr.sh debug

To test the problem, run:

mrv2 or mrv2-dbg (assuming ~/bin is in your PATH).

with a an .mp4 movie file -- size does not seem to matter (sometimes it will stop right away, other times it takes some time to do so -- it seems random):

mrv2 movie.mp4

or:

mrv2 movie.mov

The problem seems to be that EGL/Wayland freezes due to a server lock, which prevents the FLTK's timeout callbacks from running (so there's no video or timeline updates until the user interacts -- moving the mouse releases the freeze).

libnvidia-egl-wayland.so.1.1.13 seems to have solved the freezes for me. However it has problems when maximizing the window to fullscreen, leaving the title bar sometimes still redrawing it.

[Daniel van Vugt (vanvugt)]

That version appears to be in Ubuntu 24.04 so we can declare the primary issue fix released here.
