    plasmashell[1391]: The Wayland connection experienced a fatal error: Too many open files
Comment 1 Nate Graham 2025-12-16 22:20:11 UTC 
I guess you had too many open files?

Nevertheless, the fact that this can happen seems to be a source of fragility. Moving to KWin to see if there's anything that can be done there about it.
Comment 2 alerikaisattera 2025-12-17 13:06:27 UTC 
I certainly did not have many open files. This is not triggered by opening a file anyway and happens out of the blue

I don't see how spontaneous failure of plasmashell is a bug of kwin_wayland
Comment 3 Zamundaaa 2025-12-18 15:05:21 UTC 
"file" refers to file descriptors here. Are you using an Nvidia GPU? The Nvidia driver has a bug that can cause this
