Seems like a buffer size limit on toolpath highlighting

Only 6000 lines on the file sent to Chris....

Did anyone ever find out how to increase buffer size?

Bump...

I doubt this is a buffer size problem. The only difference between the colors is a color setting. If it was a too small memory buffer, I would expect the drawing to be corupt or disappear.
i would make a linuxcnc github bug report so it doesn't get forgotten.

Reviving my old thread.... I upgraded to latest master a few weeks ago and this problem is back. Well, at least I believe it was fixed before.... Any idea how to fix this?

I don't recall seeing any commit that sounded to be related to this, but there are dozens a week so might have forgotten or not noticed.
