Hi, about 2-3 weeks on all Kubuntu applications, when I hover the mouse over menu items, I notice a flicker (see pictures). If I start a Windows WM within kubuntu, the Windows apps work correctly. Can anyone help me? Thanks Kubuntu 20.04.4 LTS Kernel version: 5.4.0-107-generic           [IMAGE][IMAGE][IMAGE]
