[Qemu-devel] [Bug 1805697] Re: egl-headless crashes

[Ryan Press]

I have the same issue.  The patch (which is already included in my git
source) did not help.  I can use the command line solution but it's not
ideal as I connect to the VM from multiple computers with different
resolutions.

Also if I use "Auto resize VM to window" the VM immediately crashes with
the error:

qemu-system-x86_64: /root/qemu/ui/egl-headless.c:136: egl_scanout_flush:
Assertion `surface_width(edpy->ds) == edpy->guest_fb.width' failed.


Otherwise it is working better than I had hoped, just this small resolution 
issue.
