I've been building an app using a custom opengl class derived from the
one provided by Apple as sample : (http://developer.apple.com/samplecode/Custom_Cocoa_OpenGL/index.html
). However, if you use this view inside a split view, then "glitches"
appear as the separator is moved to resize the views. To reproduce
this behavior, use the template project as provide by Apple at the
adress above. A minor compile error is easily fixed, then open the nib
file file, duplicate the custom opengl view and embed them in a
horizontal split view (vertical separator).
Launch the demo and move the separator in a reasonably fast way from
left to right. Glitches can be seen near the separator as the left
view needs to be refreshed. This behavior does not show when resizing
I have it too in my application.
I have an iMac Intel Core 2 Duo 2.16GHz with an ATI X1600, Leopard
Whereas this behavior does not really stop the application from
working, I found it to be a bit annoying and to be honest quite
unmacish. Does anyone know why it is so and if there is a workaround ?
Besides, it may be opengl driver specific (bug or video behavior)
Thanks for advice or comments.
