SUMMARY Walking through menu in Kate I found couple issues related with drawing of submenu. 1. Unnatural increasing of drawn submenu window which looks like zoom - it happens when I walk through slowly options in main menu. 2. Big vertical squeeze of text in submenu - it happens usually when I open both submenus alternately (moving mouse cursor from one to second and back). Please look at attached short movie. STEPS TO REPRODUCE Apply: Window Decoration -> Application Menu for "Breeze" decorations. * submenu window which looks like zoom 1. Open Kate 2. Click into Application Menu (icon with three horizontal lines) 3. Walk through slowly all options from top to bottom * vertical squeeze of text in submenu. 1. Open Kate (if not yet opened) 2. Go (move mouse cursor) to Sessions 3. Walk through slowly over "Recent Sessions" "All Sessions" OBSERVED RESULT * unnatural increasing of drawn submenu window which looks like zoom. * vertical squeeze of text in submenu. EXPECTED RESULT Options in submenus should be drawing "normally" SOFTWARE/OS VERSIONS Linux/KDE Plasma: YES KDE Plasma Version: 6.3.80 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 Wayland HARDWARE Graphics: Intel Xe Graphics (integrated) Processor: Intel i7 11th Gen ADDITIONAL INFORMATION Today (2024/02/24) I applied updates in Neon.

This seems like a QtWayland bug. If wp_viewporter is disabled, then there is no glitch.

I mean is it possible to do it without compilation of code? BTW. Testing latest Arch Linux. I found this issue also in Plasma 6.3.1 (Wayland). To be detailed issue was related with "unnatural increasing of drawn submenu"
