I am using Ubuntu 26.04.1 LTS and the 24.04 AppImage version of Smath. When i use 200% scaling which is necessary with my 4k monitor lowercase letters break. While typing everything looks fine .
After pressing enter the lowercase letters either disappear completely or their font size increases drastically.

When I set the scaling to 100% in the ubuntu settings the problem gets fixed but it makes everything unbearable to use because everything is very small.
Is it possible to use Smath on Linux with scaling somehow?
