Created attachment 108440 [details] Screenshot of wrong rendering of tab content. When I switch from the Application Style to the Fonts module, the module content is not redrawn. I always see the Theme selection screen (Breeze, Oxygen, Plastik). When I switch from the Theme to the Buttons tab in the Application Style module, the tab content is not redrawn properly. See attached screenshot and notice e.g. the overlap near the decorations search bar, and the search bar itself, which is actually from the Theme tab, and the Theme tab, which is shown as selected while the Buttons tab should be shown as selected.

This issue still exists in Plasma 5.12.90 on Wayland. Qt 5.11 KDE Frameworks 5.46 Mesa 18.1 Wayland 1.15
Tested on Plasma 5.14. The bug is still there. Qt 5.11.2 KDE Frameworks 5.50 Mesa 18.2 Wayland 1.16
I've tested this with Qt 5.12 beta 3 and it might be solved with the next Qt release.
Please reopen if it returns on new Qt.
