Tooltip corruption on Qt apps

Created attachment 868634 [details] Screen recording of Kate showing the problem Since upgrading to Leap 15.5 (didn't happen on 15.4), I can see graphical glitches on tooltips for pure KDE/Qt applications such a Kate or RSS Guard, or applications that use the Qt toolkit for drawing the Ui such as LibreOffice (the problem does not happen if selecting the GTK3 interface). This problem happens when moving the mouse pointer from one button to another. In the case of Kate, for example, the tooltip will try to redraw, but fail. On other apps such as LyX it will redraw quickly so the glitches are less noticeable. Usually moving away and back the mouse pointer will successfully redraw the tooltip, but then at the next move the following tooltip will fail. I'm using the X11 session on Plasma 5.27.4. On the Spanish forums another user reports similar problems with Tumbleweed https://forums.opensuse.org/t/errores-graficos-en-los-tooltips/168171/3
Created attachment 868635 [details] Screenshot showing the problem On the attached file you can see a few screenshots presenting the problem on Kate, RSS Guard and LibreOffice with the kd5 UI.
I found the correct bug report from KDE project Morphing Popups effect: glitch when the size of a tooltip is reduced https://bugs.kde.org/show_bug.cgi?id=416048
