Description Jürgen Richtsfeld 2021-03-24 21:11:02 UTC 
SUMMARY
I'm accessing a tightvnc server running in the local net. I can connect, parts of the window is recognizable, but colors are (somehow wrong) and additionally parts of the vnc window are flickering. Contained text is partly readable.
All of that worked very nice when I was on X. When using gvncviewer to acccess the same tightvnc server the UI looks ok (but I'd prefer krdc for a lot of reasons)

STEPS TO REPRODUCE
1. have some tightvnc server and connect to it
2. observe UI glitches



OBSERVED RESULT
UI glitches and flicker which renders the application unusable.

EXPECTED RESULT
Correct remote UI just like on X.

I faced that issue today. I have a container with a running VNC server and Google Chrome. When I tried to connect using krdc it's hard to recognize anything.
