unset GDK_SCALE GDK_DPI_SCALE works for me. It was GDK_SCALE=2 GDK_DPI_SCALE=0.5 as KDE would have set.

I'm using a hidpi screen, and therefore use those environment variables in order to have GTK+ apps properly scaled: GDK_SCALE=2 GDK_DPI_SCALE=0.5 However, QEMU, when launched with "-display gtk,gl=on" option, doesn't scale the window content properly, as seen on the attached screenshot. Switching to "-display gtk,gl=off" and "-display sdl,gl=on" makes it work fine. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1799792/+subscriptions
