Mouse events broken on linux

If any linux guys have input on these I would appreciate it. Observed with 64bit Ubuntu 14.04 under VMWare Player VM in Windows 7.

• Mouse hover events are not registering at all to the graphics view, eg. ui elements that have Qt styles for hovering are not being triggered. Might be that mouse move events are not triggering at all, which would cause this.
• Mouse right click drag is so fast that few pixel drag will flip the camera around multiple times. This might be something related to the mouse cursor hide + force centering mouse on the main window while dragging.

Also I'm using Qt 4.8.5 or 6. Anyways almost the latest 4.8 release. We use the same one for mac and windows and this is not a bug there.
