Bug ID: 438154
Summary: Display Configuration KCM screen description is too
large for portrait oriented screens
Product: KScreen
Version: 5.21.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common

A screenshot showing the issue
SUMMARY
The screen description for monitors with EDID is too large and overflows the
display configuration screen representation boxes, when used with vertically
oriented externally attached screens. See attached screenshot.
STEPS TO REPRODUCE
1. Connect an external screen with EDID support.
2. Open the Display Configuration KCM
3. Set the external screen to a portrait (vertical) orientation.
OBSERVED RESULT
The screen description text overflows the screen representation box.
EXPECTED RESULT
The screen description should fit properly within the screen box. If there is
more text that actually needs to be presented, the text can be truncated with
an ellipsis and shown with a tool tip.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.22.80
KDE Frameworks Version: 5.83.0
Qt Version: 5.15.3
ADDITIONAL INFORMATION
The problem was detected in a wayland session. I'm not sure if it is wayland
related.
The problem was detected when using the default size of the System Settings
application. Increasing the height of the window (almost to the available
height of a 1920 by 1080) makes the problem kind of go away - the screen
position configuration UI uses the available height to scale up the screen
representation boxes to the point where the text is readable, though padding is
a bit weird.
Here is the full EDID for one of the screens shown in the screenshot (the two
external screens are identical):
