Hello,

Today I tried to put 2 GlCtrl in one Frame. It's working but the second GlCtrl is not refreshing properly.
I have to perma-resize the Window to make refresh the second.

Here you can take a look of what I'm saying: https://imgur.com/a/D0tsFNV

Is it normal ? How Can I fix this ? (I don't think that overwriting Paint method could be the solution)

Thanks in advance

Well, the fastest way to fix this is to provide a testcase

I will check and either tell you what is wrong with your code, or (more likely) will fix GlCtrl.

Thanks,

Mirek
