Shows the thin line that happens when opening xwaylandvideobridge

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Have a double monitor setup using the Gnome Desktop environment
2. Open XWaylandVideoBridge
3. (Optional) Use and terminate screen-capture and the white line extends down the entire left side of the monitor

OBSERVED RESULT
A thin white line is present in the top left corner of the secondary monitor, it expands down the entire side if screen-capture is activated then terminated

EXPECTED RESULT
The program would be running in the background, but the window would be invisible until a program tries to screen-capture

SOFTWARE/OS VERSIONS
OS: Arch Linux x86_64 
Kernel: 6.5.5-arch1-1
DE: GNOME 44.5 (no themes or extensions enabled)
WM: Mutter
Windowing System: Wayland
GPU: Radeon RX 6800XT

ADDITIONAL INFORMATION
I saw this behavior on Gnome 43 as well, and also with the AUR version of XWaylandVideoBridge

My primary monitor is 1920x1080p239.76Hz SDR landscape on right side, the secondary monitor is 2560x1440p94.89Hz SDR portrait-right on left side

Shows the linme of white pixels that appears when XWaylandVideoBridge is running

STEPS TO REPRODUCE 
1. Have a single monitor using the Gnome Desktop Environment
2. Open or have running in the background the XWaylandVideoBridge

OBSERVED RESULT: 
A thin white line is present at the top-left corner, the same length as an icon tile.

EXPECTED RESULT: 
No such line should be present

SOFTWARE/OS VERSIONS
OS:  Nobara Linux 38
Kernel: 6.5.9-201.fsync.fc38.x86_64
DE: Gnome 44.2 (extensions enabled)
Extensions Enabled: 
AppIndicator and KStatusNotifierItem Support
ArcMenu
DashToPanel
DesktopIcons NG
GameMode
Just Perfection
Wireless HID

Windowing System: Wayland
GPU: Radeon 7900 XTX

Additional Infromation:
This white line disappears if a window is placed over it, a game is started, or when moving to an alternate workspace. However, when returning back to the desktop environment or the default workspace, the line reappears.

Monitor is a 240Hz 2560x1440p SDR landscape.

ADDITIONAL INFORMATION
Depending on my screen layout, the thin white line appears on the main screen instead of the left most one and is in reality a white square.
