We are experiencing an issue after applying themes to a complex application. We are seeing a noticeable delay in window opening response times between no theme and a theme being applied. On some windows the opening delay is approximately 1 second. Admittedly the window is very busy and complex.
Looking at window resource monitor most of that extra delay is after the data has been retrieved (i.e. network traffic stops).
There is some overhead in our code in the DW constructor event but that only accounts for a small percentage of the delay.
In some instances the window goes completely black for a moment before rendering.
Has anyone else experienced performance issues?
*Edited* Just edited to draw attention to this, the performance issue has caused the customer to roll back the Themed version. It would be good to get some feedback.
