Bug ID: 483819
Summary: If the system's configured scale is above 100%, some
apps' elements will draw way too big, unless XWayland
is used
Classification: I don't know
Product: kde
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: morcyboll...@gmail.com
Target Milestone: ---
Created attachment 167364
--> https://bugs.kde.org/attachment.cgi?id=167364&action=edit
Demonstration of the bug in LibreOffice. The lower screenshot shows the
expected appearance, achieved with the XWayland workaround.
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
STEPS TO REPRODUCE
1. Go to System Settings > Display & Monitor > set Scale to 125%
2. Open LibreOffice and check out the size of the toolbar and other elements
3. Open any image in Gwenview > Show Editing Tools > Annotate and check the
size of the toolbars on the left and on the bottom
OBSERVED RESULT
All elements of the windows are scaled up way above 125%. As a result, they
take up a notable part of the screen. Some QT layouts end up bigger than their
windows, making elements inaccessible.
EXPECTED RESULT
Apps should be scaled to the configured scale of 125%, and all elements should
fit within their respective windows.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Arch Linux 6.8.1-arch1-1 (64-bit)
(available in About System)
KDE Plasma Version: 6.0.2
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
ADDITIONAL INFORMATION
This problem has appeared after upgrading to Plasma 6.
The workaround I've found for this is to force QT to use XWayland on per-app
basis, for example: "QT_QPA_PLATFORM=xcb libreoffice --calc"
Gwenview's Annotate behaves weirdly even though Spectacle's Annotate behaves
normally (i.e. correct scaling is applied), but I wasn't able to get Spectacle
to screenshot itself. Attached is a demonstration in LibreOffice.
