felipemoreno <felipemoreno1...@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |felipemoreno1...@gmail.com --- Comment #15 from felipemoreno <felipemoreno1...@gmail.com> --- I have a very similar issue in Plasma 6 with Fedora 41. The issue include not only hovering over Task Manger Icons but also Desktop Effects: Overview and Desktop Grid. All of these show blank window thumbnails. The thumbnails include the application icons, but no a window preview of the application.
