    I am noticing some "artifacts" when maximizing or resizing a window using docked panels. There are blocks of dead space that appear temporarily, and one control we are using dances around quite a bit before settling down (it's being redrawn frequently and it doesn't draw quickly).

    What can be done about these artifacts? We're using the Q2 2008 codebase.

    Is the control that "dances around" one that does not support double-buffered drawing? I have similar problems with my apps when I have 3rd party controls
    or some standard .net controls like the split container on my docking forms / panels.

    We actually found this to likely be a problem with Citrix (not a huge surprise there) and the resolution used. It's not an artifact of Telerik's doing.

    I found it to be a general prolem that shows up on some hardware configurations (older graphics cards for example, or virtualized installations).
    I'm working on a prototype application that we have deployed on a selection of older boxes - some show noticeable problems, some do not. So far I have not found the pattern.

    I suspect that there is unneeded excess drawing that does not show up on some hardware configurations. Needless to say that the forms would paint faster in all configurations if there were less unneeded re-painting.
