Created attachment 156524 [details] Dolphin's broken menu SUMMARY *** Trancparency/blur of folders panel's context menu looks broken. *** STEPS TO REPRODUCE 1. Set transparency for menus in Breeze application style in Systemsettings 2. Open Dolphin 3. Right-click on any item is the left panel OBSERVED RESULT Menu looks weird EXPECTED RESULT Menu should look like any other menu SOFTWARE/OS VERSIONS Windows: n/a macOS: n/a Linux/KDE Plasma: KDE Plasma Version: 5.27.0 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION I observe this with both Breeze and Klassy widget styles. Lightly style is not affected (it's too much different though). Can't remember if this started to happen after Plasma 5.27 update, but I'd rather blame Frameworks 5.103.0 update.

Interesting enough, I also see infamous "corners" bug for menus in Dolphin, but that (and the menu translucency thing) affects only my Manjaro install, and does not affect Tumbleweed VM. Probably some old config-related thing?
Couldn't reproduce it in Wayland session, it happens under X only.
I've seen this on some of my systems as well. After deleting .config/breezerc the menu did look normal but the corners appear to have a dark dot. I do not see this for other context menus in dolphin.

Re-setting menu tranparency recreates [Style] MenuOpacity=.. entry in ~/.config/breezerc and the weird look shown in the inital report is back.
