Public bug reported:
Setting the screen resolution explicitly from anything instead of the
default 800x600 resolution while Disco Kubuntu is booted from a virtual-
machine (Virtualbox) is met with the resolution switching quickly to
what's expected followed by it immediately switching back to 800x600.
Testing this in GNOME afterward is not met with this bug.
==== Guest Additions (proprietary) testing ====
(This utilizes the proprietary guest addition add-ons from Virtualbox to
further test the limits of the bug, but since the guest additions are
proprietary additions to the operating system, I am separating it.)
With Guest Additions installed, Plasma is able to stay with the auto-scaled
resolution correctly, but setting any specific resolution is met with it
switching back to the auto-scaled resolution much like how it would switch back
to 800x600 earlier. GNOME is still able to switch to other resolutions without
any problem with Guest Additions installed.
==== ====
I am unable to test if this bug affects actual real machines and
hardware or if it is a virtual monitor specific bug.
I was using the KDE Displays settings GUI (kcmshell5 kcm_screen) while
encountering this bug.
