Bug ID: 414924
Summary: Distorted window on Hidpi Screen
Product: kmail2
Version: 5.12.3
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: UI
Assignee: kdepim-b...@kde.org

kmail 2 distorted main window on hidpi screen
SUMMARY
This is a multi-monitor setup
Primary Monitor: Eizo EV2785 3840x2160
Secondary Montor: Eizo S1910 1280x1024
Scaling factor is set to: 1.5
STEPS TO REPRODUCE
1. Start KMail on the primary screen, in fullscreen the window
is distorted (see screenshot kmail2_distorted_hidpi.png), resizing leads
to more distortion.
2. Move the window to the secondary screen and double click to maximize it.
The distortion goes away (see kmail2_secondary_screen).
3. Moving it back to the primary screen leaves the layout exactly as on the
secondary screen, only scaled to the higher resolution (smaller).
4. Resizing or maximizing the window again (on the primary display) gets the
distortion back. The Kmail window seems to be cut off on the left and the
date part of the message list is repeated on the right.
OBSERVED RESULT
Distorted window on the hidpi screen. Undistorted window on the secondary
display.
EXPECTED RESULT
Undistorted window on both screens
