Dear all,
I've noticed a strange electron density asymmetry on the pictures provided by the pngModule.

As an example I'm using PoG 0.2.1 standard LWFA example with all default settings.  The computational grid is specified like `TBG_gridSize="-g 128 256 128"` with no moving window. I have noticed that the shape of the wake wave is not circular in the transversal direction. Please find a picture attached to illustrate the issue. 
It looks a bit strange to me as the laser pulse has a circular polarization and grid size/step are the same in both transversal directions. This "rectangular" shape of the wake wave puzzles me a bit...

Best regards,
Danila.
