TabbedComponents mingle/blend graphics in VST2 + Reaper 64 Bit

Hi everybody,
I use a TabbedComponent in a VST2 PlugIn. When I switch between two tabs, the tabs graphics mix with each other in a very weird manner. VST3 works as expected. Tested this in Reaper so far.

Has anybody experienced similar problems and came up with a solution?

Can you post a simple piece of code that reproduces this?

Hey Ed.
Thanks for the Reply. I have found the Solution just now. I put a setAlpha(0.5) in the PluginEditors constructor, which causes the old components to be visible in the background. Leasing it solved the Problem. I will try to boil it down to a simple example and post it here, for future reference.

Regards,
Tobi
