Just don’t be harsh! I just wanted to give you a clue observation that may lead to fixing the bug. It may or may not be helpful. Imho it’s better first finding the cause of the bug instead of reengineering without knowing what the problem is in the longtime.
I’m just reiterating what people have been telling me for the past few years while trying to get clarity on the issue you are currently facing. I had given up after being told it was expected behaviour for so long (while seeing many non-juce plugins using openGL without the issue).
I’d actually love to be wrong on this and have it fixed.
