Bug ID: 412552
Summary: Extended screen on 2 displays overlaps by 1px
Product: kwin
Version: 5.16.5
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: multihead
Assignee: kwin-bugs-n...@kde.org
Reporter: el...@seznam.cz
Target Milestone: ---
SUMMARY
I have 2 monitors, I use extended display. When I configure them next to each
other, they overlap by 1px.
STEPS TO REPRODUCE
1. Connect 2 monitors
2. Make extended workspace
3. Configure secondary monitor on right and snap it to the main monitor.
4. Set separate wallpaper for each monitor
OBSERVED RESULT
If I click on primary (left) monitor, I can see 1px of wallpaper on secondary
(right) and vice versa.
EXPECTED RESULT
Screens do not overlap.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon 5.16
KDE Plasma Version: 5.16.5
KDE Frameworks Version: 5.62.0
Qt Version: 5.12.3
ADDITIONAL INFORMATION
I'm using X11.
Primary monitor has width of 1920px, so I assume it is placed at coordinates
0-1919. Secondary monitor is configured at coordinates 1919-3839. So this would
mean that pixels at 1919 are actually displayed at both monitors showing 1px
overlap. Shouldn't secondary monitor start at 1920?
This might have relation to Bug 339602.
