[Paraview] pvpython WriteImage output corrupted

[Masquelet, Matthieu (GE Global Research)]

I have experienced similar issues to a lesser level. Say if I'm looping over 20 files to generate snapshots for a movie, sometimes, 1 or 2 of these will be corrupted in a fashion similar to what is reported here. Also using 3.98.1 on Linux 64-bit, writing png files.

Hope this helps,

Matthieu

I should also add that I can output images from the ParaView GUI in the linux machine with no problems.  It's just pvpython WriteImage output that is corrupted.
