<div dir="ltr">Here is an easy way to reproduce the error I'm talking about. On ImageJ, create an 8-bit image of size 630x950x1500 (approx 900Mb) and save it as "test.tif".<div><br></div><div>On PV, open the tif file and click "Apply". Now, change the visualization mode to Volume. Try to rotate it. At this point PV crashes.</div>
