Irrlicht render to texture problems

[agamemnus]

I have several issues when I render to texture in Irrlicht in DirectX9 mode, and some of them could be traced back to CEGUI. I am not sure if CEGUI is causing these two particular issues, but it seems likely.

First, the text for the cities is rendered with CEGUI windows. They are offset incorrectly. The flag images (Irrlicht) are also offset incorrectly, but it seems CEGUI offsets them even more.

Second, when I open a different window (like the red window in the pic), all of the GUI elements except the city name text disappear. (I tried this test without having the "Merchants" window open, and all the other GUI elements -- the city name text, money counter, and the slider at the bottom-right, appeared, though their position was off in the same was as the text)

I don't really know what's going on here.

I figured out problem 1: the offset problem is there because the render texture is automatically scaled to the next biggest power of two (800x600->1024x1024), and draw2dImage gets confused.
