I use another extension called Workspace Matrix, there were no issues with these two until I updated to Gnome 45. If you look at the attached screenshot you can see what is the new unexpected behavior (semi transparent white rectangles that start at the top-left of each "workspace preview" and extend down and right to (or beyond) the bottom-right corner of the screen.
It did not do this in Gnome 44, it only does this when Blur My Shell is enabled.
