Description
QGIS 3.4.1 under Windows still give problems with some GRASS 7 algorithms that call GRASS scripts, like r.mapcalculator or r.fillnulls, that call other GRASS scripts during execution.
https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/grass7/Grass7Utils.py#L396
For instance r.fillnulls:

The new r.mapcalculator (https://github.com/qgis/QGIS/pull/8444) have the same problem under Windows.
This seems somehow related with these already closed tickets: #16186 #20146 #20281
