Hello all,


I have continuing issues with display artifacts from drop down menus.
Across all applications.


Photo showing behavior: https://www.dropbox.com/s/hc7if1kjgu..._3461.JPG?dl=0
-> twitching mouse to other drop downs and back generally clears issue
-> happens consistently from boot through many days of work uptime

Suggestions are most appreciated.


Having used various Linux distributions for 15+ yrs, this setup with OS
42.3 and Plasma is very compatible with my productivity and engineering
software (including VMware WS-Pro). A real pleasure to use.
