Bug ID: 510755
Summary: Adding virtual output in OBS Studio moves panel to
non-primary monitor and setting to choose primary
monitor disappears
Classification: I don't know
Product: kde
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
I'm not sure if this is an xdg-desktop-portal bug, a KWin bug, a Plasma bug, or
even an OBS bug.
I have two monitors:
* primary monitor: left ultrawide on HDMI
* other monitor: right full HD on Display Port (with an HDMI->DP adapter)
When I open OBS Studio, click on the + Add Source button, select Screen Capture
(Pipewire), and then choose New Virtual Output, the virtual output that gets
created shows up on the Display Configuration KCM to the right of the other
screens, but my panel moves to the right monitor.
Additionally, the radio button used to choose a primary monitor in the Display
Configuration KCM disappears.
In the kscreen-doctor outputs list, it doesn't seem that the second monitor is
considered the primary monitor, though, as the priorities are correctly are set
as 1 -> 2 -> 3.
STEPS TO REPRODUCE
1. Have two monitors
2. Set left monitor as primary one
3. Open OBS Studio
4. Click on the + Add Source button
5. Select Screen Capture (Pipewire) in the screen selection dialog
6. Choose New Virtual Output
7. Inspect System Settings -> Display & Monitor -> Display Configuration
OBSERVED RESULT
1. Panel moves to other monitor
2. Radio button to choose Primary monitor disappears
EXPECTED RESULT
1. Panel stays in the same place
2. Radio button to choose Primary monitor doesn't disappear (not sure if
intended ???)
