I've just updated to Vuforia 5.0.6 in my iOS app. I was running Vuforia 4 before, with no issues at all (except for the black screen in iOS9).
Now, I'm having another issue (a new one): when I lock the screen, I can get one of these two EXC_BAD_ACCESS:
1. glFinish() -> within the finishOpenGLESCommands method
2. [self.context presentRenderbuffer:GL_RENDERBUFFER]; -> within the presentFramebuffer method
Just for the record, the app and the lines mentioned before where working perfect before updating to Vuforia 5.0.6.
Any idea of what might be happening here? Did the latest update change something else not documented in the migration guide?
