Title:
  Distortions in OpenGL preview

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  Sometimes distortions appear in the openGl preview (see attached file). These distortions affect the texture as well as the identify-border and can be found at some but not all of the edges of single images. The positions of the distortions is always the same if the openGl preview is opened and closed as long as the image parameters stay unchanged. Projection is equirectangular and the images are "fishey fullframe" type at 15mm, 1.0 crop. With images of different type (ie. 10mm rectangular at 10mm/crop 1.6 or fullframe fisheye at 20mm, crop 1.0) there seem to be no distortions.  On different Systems the distortions are not present, weaker or different.

The Hugin Built 3784 has been used but older builts seem to be affected as well
