--- Comment #1 from Stefan Hoffmeister <stefan.hoffmeis...@econos.de> ---
I added
```
export QT_LOGGING_RULES="kwin*=true"
```
and whenever I resize the virtual screen from the host, I get
```
Dec 03 19:50:30 fedora kwin_wayland[7208]: kwin_wayland_drm: Received change
event for monitored drm device "/dev/dri/card0"
Dec 03 19:50:30 fedora kwin_wayland[7208]: kwin_wayland_drm: Could not find
edid for connector DrmConnector(id=38, gpu=KWin::DrmGpu(0x558b1858c490),
name="Virtual-1-unknown", connection="Connected", countMode=25)
Dec 03 19:50:30 fedora systemd[1]: vboxclient.service - VirtualBox guest VMSVGA
resize client was skipped because no trigger condition checks were met.
```
The last log entry I just left in to show that the Oracle VirtualBox resize
client is being skipped (as expected).
`drm_info` has this to say:

highlighting that there indeed is no EDID data.
