Description of problem:

After booting the updated Fedora 39 to 40 Workstation, a white rectangle in the top left corner of the desktop appears (right below the activities button).
It seems that the problem is related to xwaylandvideobridge.


Version-Release number of selected component (if applicable):

xwaylandvideobridge Version 0.4.0-5.fc40


How reproducible:

The described rectangle appears at any login into a gnome session in the first virtual display (not on any other display).


Steps to Reproduce:
1. uninstall xwaylandvideobridge (dnf remove xwaylandvideobridge)
2. relogin
3. the white rectangle described has disappeared from the upper left corner of the first virtual desktop

This is also affecting me on my Fedora 40 GNOME login; uninstalling xwaylandvideobridge removed the rectangle.

Comment 2 le.poittevin.laurent 2024-05-31 17:43:33 UTC
This is also affecting me on my Fedora 40 GNOME. Stop the xwaylandvideobridge process removed the rectangle.

Comment 3 Youri 2024-07-30 19:52:46 UTC
Also me on Fedora 40 Workstation, after installing KDE Plasma via: dnf install @kde-desktop-environment
Subsequently the white rectangle showed up, without yet having switched between Gnome and KDE.

Removing xwaylandvideobridge solved the problem: dnf remove xwaylandvideobridge

It might be best to report this upstream. Can anyone do that, please? (Add link it here).

Looking at that link, it seems there have already been posted similar issues there, that were closed with a reference to a bugtracker at https://bugs.kde.org/buglist.cgi?component=general&product=XWaylandVideoBridge&resolution=---

There are already at least 2 issues opened there for this problem. This one looks to best match what people describe here on RH bugzilla:

https://bugs.kde.org/show_bug.cgi?id=485604

We should probably add ourselves to the CC list there as well, so it gets noticed?

Thanks for finding it. Yes, you can CC yourself and perhaps add a comment stating that many users are affected (possibly link here to this bugzilla or Fedora Discussion [1]).

I saw your reply after I posted a comment there, but have now added this Fedora forum link as well. Thanks.

Hy there

i do also see this on my Fedora-F41 workstation running a gnome desktop after login with not application started.Xlssclients show these components:

$ xlsclients 
buster  gsd-xsettings
buster  ibus-x11
buster  xwaylandvideobridge
buster  mutter-x11-frames

It is still there! I am running gnome on a AMD Ryzen 7 5700G workstation with 3 attached 4k monitors.
The white rectangle is sometime displayed after a fresh boot-and-login on gnome.

GroovyMan left most screenshot with that weired white rectangle

This white rectangle appears only on the left display in the first virtual screen. Looks like an window of an orphaned service/application.

Comment 10 Aoife Moloney 2025-04-25 10:33:41 UTC
This message is a reminder that Fedora Linux 40 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 40 on 2025-05-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '40'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 40 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 11 Aoife Moloney 2025-05-16 08:13:33 UTC
Fedora Linux 40 entered end-of-life (EOL) status on 2025-05-13.

Fedora Linux 40 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
