Just now the small title text on applications in the application launcher became glitched, as well as the section titles (favorites, recent, etc). It happened on each section except for the applications in Recent (though the "Recent" text is a gray blocky nothing like the rest). Reproducible: Didn't try
Created attachment 101159 [details] Hold the cursor anywhere within the box except for over the top item, and this happens.
Created attachment 101160 [details] If you the cursor goes over the top item, this happens.
I logged out and back in just now, and was able to reproduce it once, but I didn't record it. I logged out and back in again, started OBS first, and then tried to trigger it again, but now it won't happen.
Cannot confirm this bug in: Distribution: KDE neon Developer Edition Unstable Branches KDE Plasma Version: 5.10.90 KDE Frameworks Version: 5.37.0 Qt Version: 5.9.1 Kernel Version: 4.10.0-32-generic Video card: Intel 4500MHD
I can't test it, I don't have KDE available at this time (Solus) but I'd bet that that bug wouldn't be reproducible by anyone on a more recent version.
Text in Kickoff is rendered via QtQuick. If this shows rendering errors, the bug is either in QtQuick, or in the OpenGL drivers.
