I'm using AvalonEdit in my WinForms application. AvalonEdit is placed onto control with ElementHost on it. Application has RadDock from Telerik and AvalonEdit can be placed on its windows. Often I get problem with ElementHost repainting. I don't know all the symptoms, but I can reproduce this problem by changing focus and moving other windows over the editor. After this all WPF controls in my application become broken and can't be repainted. The only way to force to redraw ElementHost is resizing. I can change for example width and WPF control will be redrawn. But this "solution" is not acceptable. The problem can be reproduced for docked or floating windows, for windows with active scrollbars or without, on x64 and x86 machine. To "fix" ElementHost I need to restart application.
Have somebody any suggestion for me?

At least check if the problem disappears when you don't put it in a RadDock. If not then you have something to talk about when you call Telerik for support. – Hans Passant Feb 06 '13 at 14:51

I have created separate application which has RadDock and AvalonEdit, and I couldn't reproduce this problem. Probably this freezing is related to counts of controls in application, or numbers of layers from MainForm to AvalonEdit. – Yuriy Feb 06 '13 at 15:04
