Dear list,
I first posted this to the quartz list, but I'm starting to think I'm the only person on it, some hopefully a Cocoa list reader can help...
I think I've stumbled upon a bug/undocumented feature in Core Animation, I've made a quick app to demonstrate the issue.
http://s3.amazonaws.com/TempStuff/LayerDebug.zip
Once the app runs, make sure you are in 'tab1', you can resize the window, scroll around, all is well (apart from the disappearing blue sublayer, but lets ignore that for now, unless anyone knows how to fix this?)
You switch to 'tab2' and back again, fine.
BUT, if I switch to 'tab2', resize the window (even a 1 pixel tweak), then go back to 'tab1', the layers are now upside down!
I want to use Core Anim in a shipping app, but obviously cannot until I sort this out, so I'd really appreciate any input.
Cheers
Moray
