Bug ID: 428990
Summary: High DPI scaling works on display :0 only
Product: digikam
Version: 7.1.0
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Setup-Misc
Assignee: digikam-bugs-n...@kde.org
Reporter: gsten...@gmx.net
Target Milestone: ---
In the settings dialogue | Miscellaneous, tab "System" there are two settings
about high DPI, "Use high DPI scaling from the screen factor" and "Use pixmaps
with high DPI resolution".
The settings work as expected if the KDE session uses display :0. However, if
digikam is started in a session using another display, it no longer works, i.e.
fonts and images are too small on a high DPI screen.
STEPS TO REPRODUCE
1. log in as first user, start digikam, set the two options named above and
restart digikam
2. observe the splash screen on startup is bigger, i.e. the option works
3. start a new KDE session with the same user and start digikam
OBSERVED RESULT
high DPI scaling no longer works
EXPECTED RESULT
should be independent of the display
