Bug ID: 442524
Summary: Windows are not placed correctly after connecting a
second screen
Product: kwin
Version: 5.22.4
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: multi-screen
Assignee: [email protected]

Target Milestone: ---
SUMMARY
It seems like KWin has issues with placing windows on a second screen. My setup
uses X and two screens with identical resolution (1080p), one is the laptop's
screen and the second is an external monitor, connected through a USB-C docking
station and a DisplayPort to HDMI cable. It is on top of the laptop's screen,
both physically and in the settings.
When I connect the monitor, KWin correctly detects it and shows windows on it,
but those windows appear to be placed incorrectly. As an example, the
application launcher opens in the centre of the screen instead of the left
corner where the related button is. Windows then appear not to be able to move
around the laptop's screen correctly, as if there was an invisible border.
Restarting KWin makes the issue go away.
STEPS TO REPRODUCE
1. Connect an external screen.
OBSERVED RESULT
Windows and widgets are not placed correctly and behave weirdly.
EXPECTED RESULT
Windows and widgets work normally.
