Comment 3 for bug 1137554

I believe I've identified what's happening.

It seems that the input candidates dialog box appears outside of the screen bounds when it is "not showing".

In a word processor like lowriter, the candidates dialog box would appear right below the text being entered. However in Inkscape it appears to be randomly placed? I realized this when I saw the top border of the dialog box at the bottom 2 pixels of my screen.

I hope that helps.
