Visual Issues With Multiple Windows

[Visc0us]

When trying to rearrange the various windows (such as colour picker, layers, history etc.) I get a weird and frustrating error where at random points on the screen, the window will jump to another place and won't let me position it where I want. 

 

Any idea what may cause this?

I never encountered this problem, instead if I open the History floating window (by clicking on the icon not with the F6 key) the tooltips are no longer displayed.

Click on Manage color palettes drop down menu and everything returns to normal.
