It seems there doesn’t seem to be an option to change this in pcbnew itself, sadly.
As I build from source: does anybody know which variable in the code I need to tweak to reduce the grid intensity? I’ve messed about with some that seemed to be related, but sadly nothing happened to the grid.
I find it to be obnoxiously bright and disturbing. It used to be much more subtle.
Was facing this in the daily build version. Too bright to my liking, ended up changing it to gray. And looks like the previous implementation. Maybe a grid line thickness that can change would be better.
I find having OpenGL mode look different to the Classic is handy for switching between them, As I find I have to revert to Classic for copper fill operations
I have added a comment to the above report. The two modes behave very differently when the copper zone is moved. There is nothing really wrong with the new way, except that the documentation needs to explain both
