Anybody has some ideas?
And idea would be to either post some code so we can take a look at it or try to reproduce the problem in a smaller example and post it ( so we can take a look at it ). I'm not sure if this has something to do with transparency or with component positioning. It is true that IE can be quite a pain the butt, still, I don't remember running into this problem before.
Some code or something would definitely help ( at least, try to somehow describe the structure of the project, did you change some additional settings or something? ).
With best regards,
We have tested in a small project, it works well with the param, and we found if we use a background image with fixed setting instead of background color, the bug gone.
We lost the round corner in our dialogs, but the bug fixed.
We have no idea about it.
