[Qemu-devel] [Bug 1788701] Re: "Zoom to fit" doesn't work with -display gtk -vga virtio

[Frederick Metzengerstein]

Well, then something isn't right here.

"Zoom to Fit" disabled: qemu starts with a small window (1:1 scale) and
resizes the window when the xserver/window manager starts (1:1 scale).
This is the sane and wanted behavior.

"Zoom to Fit" enabled: qemu starts with a small window and doesn't
resizes the window when the xserver/window manager starts. The whole
display is squeezed into the small window. The window simply ignores
resolution changes of the guest.

So either there is sth wrong with your statement: "Therefore it is not
needed to auto-resize the window" or with my setup (my window manager is
dwm, the linux guest uses modesetting as video driver).

Title:
  "Zoom to fit" doesn't work  with -display gtk -vga virtio

Status in QEMU:
  New

Bug description:
  qemu version: 2.12.1, 3.0.0

  When using -display gtk for all -vga options (std,qxl,vmware,cirrus)
  the option "Zoom To Fit" is unchecked by default and thus auto-
  resizing of the window works well; except for -vga virtio: here "Zoom
  To Fit" is checked and auto-resizing doesn't work.

  Proposal: make "Zoom To Fit" unchecked by default for virtio as well
  Extended proposal: make GTK window options configurable via parameters
