Scaling is all wrong on UHD 4k monitors - Linux

When using the Ultra 4K monitors the scaling gets all wrong.

I am writing this one as a bot has already "Resolve" my issue last.

This is not a pirated version of Minecraft. I got the launcher from the Minecraft website itself.

 

Steps to reproduce:

1. Linux
2. UHD montiors
3. use UHD montors
4. use 200% scaling (otherwise it looks so small)
5. Open Minecraft Launcher
