[Bug 1799792] Re: Broken scaling with gtk,gl=on on a hidpi display

[lilydjwg]

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

Title:
  Broken scaling with gtk,gl=on on a hidpi display

Status in QEMU:
  New

Bug description:
  Tested on QEMU 3.0.0 on Arch Linux.

  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.
