Bug ID: 479306
Summary: Screen Sharing portal freezes the screen for several
seconds with large amount of windows open. Presumably
due to this, if another app is already screensharing,
that app's screenshare will freeze.
Classification: Plasma
Product: xdg-desktop-portal-kde
Version: 5.91.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: andrej.h...@gmail.com
CC: aleix...@kde.org, jgrul...@redhat.com, n...@kde.org
Target Milestone: ---
1. Issue:
When I have many apps/windows open, and then I try to screen share a window in
Discord/OBS, the entire screen will freeze for several seconds (in extreme
cases even for 10 seconds).
2. Issue
And I believe that because of this freeze, it causes my other screenshares (be
it a whole screen or just a window) to freeze indefinitely (until I manually
re-share the same screen/window again).
Here's a video demonstration: https://www.youtube.com/watch?v=_azZ6AMHhGc
I used OBS in the steps to reproduce but it's the exact same with Discord in
chromium. So it's not OBS specific.
STEPS TO REPRODUCE (1st issue)
1. Have many apps/windows open
2. Try to screenshare a window in OBS
OBSERVED RESULT
The screen will freeze for several seconds.
EXPECTED RESULT
The screen should not freeze.
STEPS TO REPRODUCE (2nd issue)
1. Have many apps/windows open
2. In OBS create the first screenshare and select any screen/window
3. In OBS create a second screenshare of a *window*
OBSERVED RESULT
The screen will freeze for several seconds AND the first screenshare will
freeze indefinitely.
EXPECTED RESULT
The screen and other screenshares should not freeze.
