Ubuntu Mate and Codeblocks - any screen issues ...

[mahesh]

I'm getting some crazy display issues while running CodeBlocks 20.03 and wxWidgets.
Not finding any help searching the Internet so I'm wondering if there might be some clues here.
My 22.04 Ubuntu Mate runs perfectly with everything except when I run CodeBlocks.
In the IDE mode the various GUI elements seem to be erratic with corruption - not the software
I am trying to create but with the actual CodeBlock program itself.
This problem occurs with all the Window managers - Compiz, and the various Marco managers.

Has anyone experienced this or have a clue as to how to fix this?
