We have issue with RadWindow used as dialog. This problem is observed on Windowx XP only (we checked on two different computers). It's not observed in Windows 7 (we also checked on two different computers). The issue looks like this:
1) There is main window which has content which changes frequently. Doesn't metter what is on background the key point is that it changes.
2) There is dialog window created using RadWindow which covers updated area (e.g. this area is hidden by dialog).
3) Dialog window from time to time "flickers" and it's possible to see background of dialog.
In order to reproduce the issue i've created sample project
and created some screenshots. Sorry for bad quality. Screenshots were created by mobile phone because screen capture programs didn't record this issue. You can also download movie
which illustrates this issue.
We need to solution for Windows XP which eliminates observed effect.
