Created attachment 124886 [details] Screenshot of the bug SUMMARY Sometimes Kicker menu have partial transparency (as if one part of menu is transparent and other is not). This usually happens only shortly after Plasma startup. STEPS TO REPRODUCE 1. Launch Plasma 2. Open applications menu 3. Open various sub-menus OBSERVED RESULT Sometimes sub-menus have this weird partial transparency. EXPECTED RESULT Menus should be rendered correctly. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 31 (available in About System) KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.65.0 Qt Version: 5.12.5 ADDITIONAL INFORMATION My GPU is AMD Radeon RX 580, Mesa 20 from mesa-aco Copr (https://copr.fedorainfracloud.org/coprs/xxmitsu/mesa-aco/). I, however, have also witnessed this bug on older Mesa versions too, on Ubuntu 18.04 (KDE Neon) with Intel integrated graphics.
I can still reproduce it with Plasma 5.18.1 and Qt 5.14.1 on both X11 and Wayland, with Radeon and Intel graphics.
The same happens with me, it's annoying especially when moving mouse very fast over menu root items.

Can you reproduce this issue in any other Plasma pop-ups? For example, notifications, Kickoff, the System Tray, or KRunner?
Created attachment 162885 [details] krunner I'm able to reproduce a similar problem in krunner almost every time with this steps: 1. open Global Theme and switch from Breeze to Breeze Dark (or viceversa), click apply. 2. click on the desktop to lose focus then press any keyboard letter to call krunner. The suggestions have a transparent background. This happens only the first time krunner suggestions appear.
