Bug ID: 361674
Summary: X11 damage events not generated when the desktop is
exposed
Product: kwin
Version: 5.5.4
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: backend-x11
Assignee: kwin-bugs-n...@kde.org
Reporter: mcottr...@teradici.com
When exposing the desktop, e.g. show desktop or minimising the only visible
window, damage events are not generated for the majority of the desktop.
Currently I'm only seeing damage for the bottom 36 pixels.
Reproducible: Always
Steps to Reproduce:
1. monitor damage events
2. open a full screen konsole instance
3. expose the desktop
Actual Results:
damage events are only generated for the bottom 36 pixels of the display:
--------- damage event ----------
area: x: 0, y: 1164, w: 1920, h: 34
geometry: x: 0, y: 0, w: 1920, h: 1200
--------- damage event ----------
area: x: 0, y: 1198, w: 1920, h: 2
geometry: x: 0, y: 0, w: 1920, h: 1200
Expected Results:
these are the resulting damage events from performing the exact same test in
KDE4:
--------- damage event ----------
area: x: 0, y: 0, w: 1920, h: 1165
geometry: x: 0, y: 0, w: 1920, h: 1200
--------- damage event ----------
area: x: 70, y: 1166, w: 214, h: 34
geometry: x: 0, y: 0, w: 1920, h: 1200
--------- damage event ----------
area: x: 0, y: 1165, w: 1920, h: 35
geometry: x: 0, y: 0, w: 1920, h: 1200
--------- damage event ----------
area: x: 0, y: 0, w: 1920, h: 1165
geometry: x: 0, y: 0, w: 1920, h: 1200
they cover the whole display, which is what I would have expected.
