Thanks, it SEEMS it is turning off, what means visually it's not there, BUT if globally
sSkinManager1.ExtendedBorders = True
then it's effecting somehow the OpenGL repaint on THAT form too.
And The whole program is running 5-10x slower.
(If turned off globally, everything works fine)
Of course it's a bit pity, because that feature:
– looks cool
– helps “basic” users to see, witch window is at the foreground.
I know, you can not do too much about that, I'm just writing down,
if I want to use OpenGL somewhere in my app. ,
I'll have to keep that feature turned off globally.
So there is no solution for this.
