[solved] (linux) Pauses when rotating and zooming

[Wegg__]

It happens even when there are no models at all. Just a blank grid. It seems to get much worse when I'm trying to do an operation. Like extrude or tweak. . . but just loading up Wings, middle clicking to get into the spin around mode. . . it stops and starts constantly. Just to confirm I downloaded the run file for 1.5.4 and it is smooth as butter.
