Bug ID: 486416
Summary: plasma6: virtualbox and differnet scale factors on 2
monitors impacts vbox-display quality
Classification: Plasma
Product: plasmashell
Version: 6.0.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: slartibar...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
I have the following setup:
Laptop monitor 2880x1800
4K monitor 3840x2160
Since plasma6, setting the laptop screen to 125% works almost fine, until you
start virtualbox (maybe other apps as well, but vbox is a nice example here)
It is sufficient to open the virtualbox main window and change the scale-factor
of the laptop screen from 125% to 100% (other values will do as well)
Changing scale-values immediately has an effect on the vbox-window size.
This would be still fine, but if you start the virtual-machine, then the
screen-size (here: windows11) is reported way bigger - depending on the scale
factor.
This has the effect, that windows thinks it has more pixels for the area
covered by the vm-display window resulting in pixelated fonts and way too small
ui-elements.
You can counter-steer by increasing windows' scale factor as well, but the
result is never as clear as if all settings (windows and plasma) are set back
to 100%
I would consider this a bug...
Your thoughts?
