How to increase font size on linux? It is really small!

[amalgame21]

The text on linux is really small and I can barely see the texts without approaching the screen.
I am using X11 and 2K screen.
How can I increase the font size? Thanks!

I'm not sure how you generally scale your apps, but I suppose you use the Xft.dpi setting, right?

Unfortunately, this isn't yet supported in Flutter: flutter/flutter#65517.
If I remember correctly, setting the GDK_SCALE environment variable at least allows integer scaling, not great but better than nothing.

Doesn't really help you, but I can say that it scales well on Wayland, at least.
