Bug ID: 478994
Summary: A disabled screen disconnecting and reconnecting
itself causes display layout updates
Classification: Plasma
Product: KScreen
Version: 5.91.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: qlum...@gmail.com
Target Milestone: ---
SUMMARY
Whenever a disabled screen disconnects / reconnects itself, it causes the
layout to update.
Some monitors, such as in my case the Gigabyte G27Q will attempt to disconnect
and reconnect every 10 seconds or so when disabled. It will do so for roughly a
minute or so.
STEPS TO REPRODUCE
1. have at least 2 display of which one with the behavior above
2. disable the display with said behavior, alternatively manually unplug the
monitor
OBSERVED RESULT
Screen / panel layout gets updated, causing stutters / minor flickering.
EXPECTED RESULT
The display layout does not get updated, as none of the active displays
encounter changes.
This is especially problematic if you want to re-enable the displays, as it
imposes a deadline of less than 10 seconds to make changes.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: kernel 6.7
KDE Plasma Version: 5.91
KDE Frameworks Version: 5.247.0
Qt Version: 6.7
ADDITIONAL INFORMATION
I have had this issue for a while, but it was masked by other problems / with
reconnecting and disconnecting screens.
