I can not reproduce the issue with flickering RadComboBox. I tested it in both render modes - classic and lightweight. You can see the behavior on this video
. The flickering could be caused by conflict of inbuilt and custom styles sheets (if you are using such). Could you please send me a runnable project or a life URL with the reproduced issue to I can test it locally to identify an exact reason of the issue? Could you please also clarify the following questions?
- what is the tested device
- what is the tested browser
- what is the skin where the issue is reproduced
