It is known that in VirtualBox Guest Additions for Linux provide incomplete 3D hardware rendering to linux.
Unfortunately, mesa based software has OGL window rendered on top of all screen graphics. And it can not be fixed, because the 3D support is ported to Linux from other Oracle projects, and not being developed till this day.
The questions are:
1)can Paraview 5.5 use offscreen hardware rendering when saving animation from GUI?
I found an article telling to use “–force-offscreen-rendering” flag, but paraview 5.5 says it is not known.
2)Can Paraview use 2 stage offscreen->blit->screen scheme as a workaround to direct rendering problems?
