DevExpress buttons redraw problem

Help me please.

I have a stange behaviour. Sometimes, when I'm shitching between tabs in my besktop application, I face a problem with buttons repainting (refreshing) (the lable are not presented on the button). But the button redraws when I move the mouse on it.

Does anyone know the reason of this behaviour and how to fix it? Than开发者_C百科ks in advance!

Which versions of our controls are you using? I remember, there was a problem with SimpleButton painting but it was resolved in the last (11.1) version. Can you install this Suite version, upgrade your application and check how it works?
