Comment 0 for bug 2048703

Release: 23.10
Expect to happen: Run a flatpak app and it displays on the screen
What happens instead: Some flatpaks fail to display when using Wayland and Nvidia card. The icon for the app shows in the dash and I can interact with the icon (i.e. right click and quit) but the app never displays on screen. All these same apps display properly when running the log in with X11.

I'm no expert but it looks related to Vulkan. Here are the errors seen in Wayland but not in X11

Easy Effects, Weather & Resources display this:
libEGL warning: egl: failed to create dri2 screen
MESA: error: CreateSwapchainKHR failed with VK_ERROR_INITIALIZATION_FAILED
MESA: error: zink: could not create swapchain

Plexamp fails to display with the following errors:

this warning shows in both Wayland and X11 when running plexamp...

Flacon displays this (only warnings) but displays properly:
