High CPU usage when using nixos and wayland + cage #95
Description
Hi I'm using a build of the program with commit for #89 but when I run flex-launcher in nixos-25.11 it just renders a black screen and consumes a lot of cpu cycles.
It seems to detect when i press keys, so it hasn't locked up totally.
Log:
