Instaled Minecraft Icons don't scale with the rest of the interface

Description of bug

Icons don't scale with the rest of the interface

Steps to reproduce

Have a 4k display using Pop!_OS 21.04. Scale the system to 200%...
MultiMC 5 - Version 0.6.13-2519 on lin64 - MultiMC 5

Everything scales nicely, lists, buttons, menu's... But because the icons don't scale, the installed Minecraft titles are very awkwardly squashed together.

Suspected cause

I'd estimate that they stay at the original 100% size and ignore Gnome's scaling entirely.

This issue is unique

• I have searched the issue tracker and did not find an issue describing my bug.

This is because the default GNOME scaling doesn't affect Qt applications. Setting export QT_AUTO_SCREEN_SCALE_FACTOR=1 in your .profile. I forget if it's 1 or 2.

I'm not sure if this is something that is supposed to be fixed for MultiMC or just a Qt thing. @AriaanBruinsma, could you provide a screenshot of what you're seeing?
