Suppressing the white flash

[Euwiiwueir]

The patch is now merged upstream (yay), though it’ll be some time before RPMs with this change are released to stable. The color is configurable through a new gui-default-window-background-color feature:

# Substitute your actual guivm if not dom0
[user@dom0 ~]$ qvm-features dom0 gui-default-window-background-color 'dark blue'

Then start or restart relevant app qubes to have the new color applied.

Also: after upgrading you may have to kill and restart the qvm-start-daemon process in dom0 to pick up the new logic:

[user@dom0 ~]$ pkill --full qvm-start-daemon
[user@dom0 ~]$ /usr/bin/python3 /usr/bin/qvm-start-daemon --all --watch &

Context: Upgrading packages `qubes-core-admin-client`, `python3-qubesadmin` probably should restart `qvm-start-daemon` · Issue #9310 · QubesOS/qubes-issues · GitHub
