Unlikely I would think - DOS knows nothing about graphics. Also, my Win 3.1 is still running fine (just checked, using VBox v4.2.12), plus I run it on top of DOS 6.22.urbite wrote:I have my WFW 3.11 loaded on top of DOS 6.20 (instead of 6.22). Could this be the problem?
It could be some kind of driver problem. At a wild guess it's getting confused about emulating 16 color (4bpp) vs 256 color (8bpp) display modes. In 16 color modes a byte contains two pixels, is it just a coincidence the scaling is x2 ? The cause might be an incorrect init of the graphics mode, which would be why switching to text mode and back fixes it.
I don't see what networking would have to do with it.
