Dear Maintainer, There is a white line in the upper left corner of my desktop. Changing the desktop pattern does not alter it. Moving a window over it, going to the "activities" view, or going to "workspace 2" (ie 3-finger-swipe gesture), makes the line disappear. Clicking or mousing over the line does nothing. It has no negative functional impact on the system, but is irritating. I should be able to set the desktop image.

Last week I installed Debian Stable (bookworm) with Gnome in the initial installer. I used apt to install ("task-") kde, ssdm, and cinnamon. I didn't see the line in Stable gnome in wayland, stable "legacy gnome" in wayland, Stable kde in wayland, or Stable cinnamon in X. I then upgraded, using sources.list and full-upgrade, to testing/trixie. Since I have used only Gnome in wayland. The white line appeared the moment I appeared. Nothing I do affects it (except moving to workspace 2). Switching from 100% scale to 150% scale, as shown in the above image, had the effect of changing the line's size. Searching Google, I find multiple people reporting this bug on both gnome and kde https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/7212 https://www.reddit.com/r/NobaraProject/comments/1aenal7/a_thine_white_line_appears_on_the_top_right/ They say the line is caused by "xwaylandvideobridge". I don't know what that is, so I don't know what to do about it.
