Summary0004510: VTK OpenGL2 Backend: Cropping is broken with GPU Volume rendering if depth peeling is enabled
Description

Cropping is broken (not cutting into volume in 3D, just limiting the region of interest in 2D) with GPU Volume rendering if depth peeling is enabled, on both Windows and Linux.

See example video here:
https://discourse.slicer.org/t/volume-rendering-model-does-not-update-interactively-with-roi/2125/2

The problem does not occur if depth peeling is disabled.
The problem does not occur with CPU raycasting (regardless of depth peeling).

After updating the VTK used in Slicer, the cropping plane either flicker or are plain. This video illustrates the problem: https://gitlab.kitware.com/vtk/vtk/merge_requests/4071#note_395250

The issue with the boxwidget's face highlighting is fixed here:

Please test and let me know if this completely addresses the issue in slicer.

The fix for the boxwidget has been merged into VTK master.

The fix here was a fairly low-level change isolated to the boxwidget's rendering pipeline. It shouldn't be related to the reported issue 0004598.

I am now marking this issue as resolved. By building Slicer with the latest VTK, the artifacts do not appear.

Note that issue 0004508 is still pending.
