I recently run into weird redraw problems with the Forms Designer on a Windows XP Tablet Edition PC. Turned out to be related to the hardware acceleration settings of the graphics card driver. I've read that WPF can have problems with some display drivers. Has anybody experienced the same, in particular together with the Telerik Controls?
Symptoms were:
Controls do not draw correctly in designer mode
Container Controls do not draw
Cannot select the Task menu
Controls are invisible while moving them around on a Form
Workaround for now is to disable some of the HW Acceleration Features, especially Direct Draw related Settings.

Erwin

Hi erwin,

Thank you for the writing.
I tested a case similar to yours, but I was not able to reproduce the described behavior. This most probably means that you have outdated display drivers. The only thing I can suggest is to try this on another machine with different video card or with updated video drivers.
If you experience the issue on the other machine, please send me the project. This will allow me to debug the case locally and provide you with further assistance.
I hope this helps.
