I do not see

DLOG("---------------------------");
DDUMP(popup->GetRect());
DDUMP(rt);

I've split log into 2 pieces.
The first piece was generated after I clicked drop list:

popup->GetRect() = [1130, 343] - [1347, 344] : (217, 1)
rt = [1130, 343] - [1347, 615] : (217, 272)
r0 = [1130, 343] - [1347, 344] : (217, 1)

The second *big* part (added as attachment) was generated after the settings window was closed.

If I'm not mistaken, the problem is with Rect for animation. As you see in log, this Rect is 1 pixel in height. This could answer why only black line is shown. But I don't really know why popup is correctly shown after all (when window is closed).
