Strange icons in Sketcher
Apologies if this is a duplicate email, I am not seeing the previous post
We are seeing strangeness in sketcher (Creo 4.0 M020). It starts with the lines in Sketcher beinging to get larger and then icon representations changing. We have also seen line thickening in drawings. See below froma machine that is seeing issues in sketcher.

Seen on a range of Dell machines with low end nvidia graphics cards.
We have tried fixing the line width in Sketcher, but no effect.
Many Thanks for any hints
