Flex and GPU rendermode artifacts

Hi,

is there any fix for those rendering issues that occur when rendering Flex UI with GPU rendermode?

I plan using Flex for my map app where GPU rendermode really helps to move the map smoothly but this mode cause missing backgrounds on text inputs, triangles on buttons etc ... so it is completely unusable.

I have tried some invalidate methods but nothing helped.

Appreciate any suggestions and ideas!

Thank you!
