Summary: Plasma Shell glitches out after waking from sleep when
external display is set as primary - on wayland
Classification: Plasma
Product: plasmashell
Version: 5.27.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Multi-screen support
Assignee: [email protected]

Target Milestone: 1.0
SUMMARY
***
Plasma Shell glitches out after waking from sleep when using wayland- windows
leave trails when moved, wallpaper is visible on a quarter of the screen,
desktop icons "fall" behind the panel. This happens only when I am using two
displays, one external as the primary and the integrated display in my laptop
as secondary. More information below
***
STEPS TO REPRODUCE
1. Log into Plasma (Wayland)
2. Open any window
3. Put computer to sleep
4. Wake from sleep and unlock: dekstop looks normal but icons have fallen
behind the panel
5. Right click on any point in the right or bottom half of the screen: bottom
and right half of the screen glitches out, as visible in attached screenshots
6. Using touchpad gestures "clears out" window trails
OBSERVED RESULT
Desktop icons move behind the panel, bottom and half of the screen become black
or white or show a glitched wallpaper, windows leave trails behind when moved
(not in the top left quarter of the screen), these trails get cleared when
using some touchpad gestures (such as 4 finger swipe up)
EXPECTED RESULT
Dekstop icons stay in their usual position, wallpaper and window not glitched
SOFTWARE/OS VERSIONS
Linux: EndeavourOS, latest stable updates, kernel 6.1.12-zen, Wayland
KDE Plasma Version: 5.27.1
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
ADDITIONAL INFORMATION
Hardware: Asus laptop with dual GPU: integrated Vega 7 (CPU is Ryzen 7 4800HS)
+ dedicated Nvidia GTX 1660Ti.
Currently running a dual-screen setup, with an external 4K 60Hz display
(connected via HDMI) as the primary monitor, and the laptop's integrated 1080p
144Hz display as the secondary. The issue only happens when both are connected
and active, and the primary display is the secondary. It works fine if:
- Only the internal display is active
- Only the external display is active
- Both displays are active and the internal display is set as primary
I'm attaching a screenshot of both my displays, where the issue is visible in
the form of "window trails" and dekstop icons behind the panel. Dock animations
also leave trails.
I can provide more screenshots if necessary
P.S.
It's my first time reporting a bug and English is not my native language. I
hope I have done everything correctly, let me know if I can do something
better. I can also provide more information if required.
Also, thank you for the amazing work you are doing, apart from a few edge-case
bugs like this, Plasma 5.27 has been an amazing release for me
