Created attachment 119111 [details] two sample outputs of plasmashell and a screenshot I use a separate control bar on the top of my screen which shows a list of opened programs (only the ones of the current workspace). Window grouping is enabled (e.g. two kwrite instances are shown as a single button). When I hover the mouse cursor over a task bar button I get a preview/thumbnail of the program's window. I regularly - but nor always - get an empty preview when the mouse cursor is placed over a grouped button (see attached screenshot). Clicking on this empty preview window segfaults plasmashell. It seems that plasmashell also segfaults if the mouse cursor hovers long enough over the button or the empty preview. STEPS TO REPRODUCE 1. Create a new control bar 2. Add a window bar 3. Make sure grouping is enabled in window bar 4. Open two instances of the same program (e.g., open two files with kwrite) 5. Hover the mouse over the task bar entry of the program group (e.g., kwrite) 6. If bug happens: No window preview is shown, just a small (in vertical dimension) empty window 7. Hover the mouse over this window for some time or click on it 8. crash OBSERVED RESULT Segmentation fault ("Speicherzugriffsfehler") os plasmashell EXPECTED RESULT Preview window of the grouped windows SOFTWARE/OS VERSIONS Linux: Antergos (kernel: 5.0.4-arch1-1-ARCH) KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.56 Qt Version: 5.12.2
