[Help wanted] How to scale the apps?

[PhyX-Meow]

I have an 2560x1440 screen, and have these in my .zshrc

export QT_SCALE_FACTOR=2
export GDK_SCALE=2

But some apps still look small. Eg. mousepad. How can I make them scale?

My distro is Manjaro, with xfce4 installed.

By the way, is there any way to disable WSLg temporarily and so I can use back to x410.

@PhyX-Meow you can use the following entry in your .wslconfig file (e.g. c:\Users\spronovo.wslconfig) to disable guiApplications entirely.

[wsl2]
guiApplications=false

You'll then need to restart WSL for the changes to take effect (wsl --shutdown from an elevated command prompt or powershell on Windows).

Did you try using scaling on the Windows side (settings -> System -> Display)... this will scale your Linux application as well, although at the moment WSLg only support integer scale (100%, 200%, fractional scaling like 150% is currently disabled by default.)

Thanks, I set 150% in windows scale, so that's why my wsl app looks still small.
I would disable it at least for now, 200% is too big for my screen.

@PhyX-Meow , if you want to try out fractional scaling (such as 150%), please refer #23. And in case you don't want WSLg to auto scale, but prefer to let framework (such as Qt or GDK) to scale, then you can set WESTON_RDP_DISABLE_HI_DPI_SCALING=true in .wslgconfig.

@hideyukn88 Thanks very much for your advise, I will try it.
