A patch to the Minimal Sample generally gets an immediate response,
and frequently an immediate fix.
Anything else gets one of the following:
A) Demonstrate the problem in the Minimal Sample.
B) Yes, looks like you found a bug, please debug it, and tell us how
to fix it with a patch.
C) Yes, you found a problem, but I'm [not me] to busy to fix it right
now, please create a bug report on the Patch Tracker.
D) "Do this: [something]" and it will fix your problem.

I don't understand whythis is AppConsole from wxBase. I'd expect AppGUI.
Also you want to be using 2.8.11. 2.9.x is not ready for usage yet.

Perhaps, but its been on my To Do list for a long time to do a
wxWidgets port of PCB.
Take a look at this project for some example GL code in wxWidgets:
