Looks like a bug or bad configuration between host/guest. Let's

From the logs of second email:
| [ 3.201725] [drm] Initialized qxl 0.1.0 20120117 for 0000:00:02.0 on
minor 0
Quite old qxl? Would it be possible to update it? 0.1.5 was
released in 2016-12-19 [0], that's almost 5 years of bugfixing,
etc.

Maybe just updating the qxl would solve the issue but which
configuration you have set in regards to memory for qxl?
I see in the logs
| [ 3.163127] [drm] qxl: 16M of VRAM memory size
| [ 3.163127] [drm] qxl: 63M of IO pages memory ready (VRAM domain)
| [ 3.163128] [drm] qxl: 32M of Surface memory size
Not sure if driver is using UMS (old) or KMS mode on Debian...
