This is my problem, I have a high density display so I need to scale my screen to 1.5 to make it usable.

This is screen scaling feature to which I am referring:

But I also use Android AVDs which don't respond well to the screen scaling (see my post about this issue)

So what do I do about apps that break when the screen is scaled? Can I disable scaling for a specific application?

• Run QT_SCALE_FACTOR=1 to disable scaling for that application.
Example: QT_SCALE_FACTOR=1 emulator -avd n5 -verbose
Alternatively, you may consider reverting the scaling, then starting other applications with QT_SCALE_FACTOR=1.5.
