Hi,
I'm using NSOpenGLContext to optimize drawing AU plugins.
There are multiple plugins and each can have multiple instances. So each
plugin creates a global NSOpenGLContext and attach particular NSView
contexts to it, so that the textures do not need do be duplicated.
Problem: When I open one plugin, it's ok. I open a different on, it's
ok. Now I release the first one, it destroys all resources => the
second one looses its textures!
I checked that both context are different, sharing is different, they
both use makeCurrentContext in both lockFocus and drawRect. Any ideas
what is wrong here?
Btw.I got the same thing working using AGL and WGL (on Windows), both without problems, so it is just Cocoa as usual.
