Repro Steps

When I use the GUI, I usually see error messages related to rendering, but they don't generally affect usage:

> gz sim
WARNING: dzn is not a conformant Vulkan implementation, testing use only.
WARNING: Some incorrect rendering might occur because the selected Vulkan device (Microsoft Direct3D12 (NVIDIA GeForce RTX 3070)) doesn't support base Zink requirements: feats.features.logicOp have_EXT_custom_border_color have_EXT_line_rasterization

> emacs

WARNING: Some incorrect rendering might occur because the selected Vulkan device (Microsoft Direct3D12 (NVIDIA GeForce RTX 3070)) doesn't support base Zink requirements: feats.features.logicOp have_EXT_custom_border_color have_EXT_line_rasterization

However, recently when using gnome-font-viewer, I encountered the following:

libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI3: Screen seems not DRI3 capable
WARNING: dzn is not a conformant Vulkan implementation, testing use only.
WARNING: Some incorrect rendering might occur because the selected Vulkan device (Microsoft Direct3D12 (NVIDIA GeForce RTX 3070)) doesn't support base Zink requirements: feats.features.logicOp have_EXT_custom_border_color have_EXT_line_rasterization
MESA: error: Failed to attach to x11 shm

It displays a transparent box, making it unusable.

Expected Behavior

I hope there is a solution to open gnome-font-viewer. In fact, I don't really understand graphic rendering and am not sure whether the problem lies with OPENGL, MESA, dzn, or Vulkan.

Actual Behavior

MESA: error: Failed to attach to x11 shm

try ln -sf /mnt/wslg/runtime-dir/wayland* /run/user/0/ dbus-run-session gnome-font-viewer

I have only one folder named 1002 under my /run/user directory, so I used the following command:

> noglob sudo ln -sf /mnt/wslg/runtime-dir/wayland* /run/user/1002/
> dbus-run-session gnome-font-viewer

However, the following error was still thrown:

Any updates on this ? I am getting this warning on python3 matlib plot.
