Comment:
Perhaps related, I have had this issue and an even more egregious variant where entire applications launched from alacritty would disappear.

On Fedora 31 Gnome Wayland. Optimus laptop with zram constantly being utilized. Discrete GPU was turned off in bios at the time.

Solution was to turn on the discrete GPU and use Nouveau. I suspect that for whatever reason the Intel GPU <-> system memory interaction was handled more poorly than with Nouveau somehow mediating it. The switch solved other graphical problems when memory was being full too (stuttering sound in videos + kernel cpu utilization through the roof), which ironically was what I wanted to avoid by turning off the discrete GPU to begin with.

Alacritty uses graphics elements which probably makes it subject to GPU memory constraints in some way.
