Weird Crosshair Gnome Desktop

I am on Debian Buster amd64 with gnome-shell 3.30.1-2. I just did some updates and noticed that I now have this crosshair pattern on the desktop/background.
Does anyone know why this pattern, seen below, has appeared?




  • Testing featured that was left enabled?

  • New window organization hint?

  • Weird plugin on my part?


Thanks!

  • Does the pattern survive when you change the background image?

  • No. The cross is gone if I change it to another background. The background previewer seems to think that that particular (default) background has a cross on it.

  • If I reselect the default background, the cross still appears. I checked out all the images in /usr/share/wallpapers . None of those SVGs show a cross in them using eog viewer. Maybe a Gnome background SVG rendering error?

  • There's a similar cross near one of the corners of the lower left preview as well.

  • Compare this question that involves PNG and Windows: Invisible PNG Image Layer that is only visible as a background. Can something similar happen with SVG and Debian? It's worth investigating.
