So you probably understand that drawing delays do not depend on whether it is a debug or a release build.
If you've built wx in debug (without optimizations) it is not unreasonable to expect drawing delays.
1. So do you reproduce the problem when using an official night build release?
To quote myself:
2.
Can you reproduce the same problem in the aui wxWidget sample?
You can ignore questions which might be relevant, but then why would you start a topic about a problem?
p.s. This happens a lot lately. I ask some questions, the OP ignores them, so I'm switching to spectator mode.
p.p.s. There are two numbered questions in this post, if I don't get an answer to at least one of them it is spectator mode for me.
