Bug ID: 527929
Summary: Wayland: window content offset vertically on
non-primary screen, bottom title bar cut off
Classification: Applications
Product: yakuake
Version First 26.08.2
Reported In:
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
On a two-monitor setup under Wayland, Yakuake's content is rendered too low
when the terminal is opened on the non-primary screen. The window occupies
the expected area, but its content is shifted down by roughly 45-50 px:
more terminal lines are visible at the top, the tab bar is pushed down, and
the bottom title bar (pin / menu / close buttons) is cut off entirely.
On the primary screen everything is rendered correctly.
The offset follows the primary screen: after swapping the primary screen
(kscreen-doctor output.<name>.priority.1), the bug appears on the other
monitor, which is now the non-primary one.
STEPS TO REPRODUCE
1. Two monitors, same resolution (1680x1050), scale 100%, side by side.
2. Plasma Wayland session, Yakuake height 80%, opens on the screen
with the mouse cursor.
3. Open Yakuake on the primary screen -> correct.
4. Open Yakuake on the non-primary screen -> content offset downwards,
bottom title bar not visible.
OBSERVED RESULT
Content shifted down by ~45-50 px on the non-primary screen, bottom
title bar with buttons cut off (see screenshot 1 vs. screenshot 2).
EXPECTED RESULT
Identical rendering on both screens.
ADDITIONAL INFORMATION
- Running Yakuake via XWayland (QT_QPA_PLATFORM=xcb yakuake) renders
correctly on both screens -> issue is specific to the Wayland code path.
- Setting animation duration to 0 ms does not change the behaviour.
- Toggling "Let window manager manage the sliding" does not change the
behaviour.
- Plasma panel is on the primary (left) screen.
- The issue moves with the primary screen when the priority is swapped.
