Problem with mouse position analysis in fullscreen?


In fullscreen mode, the tooltips don’t appear in my UI (slate/c++) and when i pick up colors on a colorspectrum, i only get shades of gray instead of colors.

All this works very well in windowed mode (packaged game).

It’s like, in fullscreen mode, ue4 had trouble picking up the position of the mouse for some tasks, like tooltip and colorspectrum. The rest of the interface works well: i can click buttons and go into editable text even in FS mode.

This occurs at least on windows 8.1 (my computer) and 7 (some friends computers).
