Bug Description

When using qimpanel on a high-dpi screen, its window position is ½ of the position of the insertion point. It uses device and UI coordinates incorrectly.
When you edit text in the center of the screen, qimpanel will appear offset to the top left; when you edit in the bottom right corner of the screen, qimpanel will appear in the center.

Ibus-pinyin does not have such a window position problem, but it seems not to be shipped anymore by default in 15.04. Ubuntu offers the ability to develop for and test this (= set the UI scaling factor to 2.0) since already before 14.04.

Ubuntu version: ubuntu-15.04-desktop-amd64.iso
package version: default version of qimpanel on the disk image

Here a screenshot from the live CD. Sorry that the image has smaller dimension, gnome-screenshot has no option to record at device resolution.

what will be happen if you switch to other IM engine like google pinyin or sunpinyin?
