#16436 new defect
windows drag and resize slowly, up to several seconds behind mouse. performance otherwise is fine. — at Initial Version

Description
when using os x (10.12.2) as the host and linux guests, gui performance is ok, except for dragging or resizing windows within the gui. then it takes several seconds for the windows to move or resize following the drag event. drag and resize both seem a little faster horizontally and vertically. horizontal is sometimes almost at normal speed.
maximized apps (full screen) are not affected by this bug and will resize with the virtualbox window in both directions as fast as can be expected.
the only exception is ubuntu desktop, and only when guest extensions are installed. then performance is fine. gnome-desktop, in ubuntu, debian, or red-hat, still has the bug. all other desktops or window managers ive tried also show this bug, lxde, xfce, fvwm, and kde
windows and linux hosts are not affected.
to see the bug, just run a live installer like fedora, debian, or red hat. open an app window and try to drag it around. you can even run the mouse in loops or circles than sit back and watch the window follow its trail.
with debian and lxde, installing guest additions sometimes temporarily solves the issue, but then it spontaneously comes back.
mac is a late 2013 retina with hybrid intel/nvidia graphics.
