after checking the changelog for 2.34, it turns out this change was made intentionally after a different user complained of black contours...viewtopic.php?f=39&t=31554
which was actually something i had already pointed out, but it was never addressed...viewtopic.php?f=34&t=28032&start=15#p122334
the proper way to fix this is to remove both the bevel edges AND black contours, to give us a truly flat minimal look--which is what i have been requesting.
i really don't like the current bringing back of the bevel edges, especially since it looks bad [like visual junk] against a black theme background, as seen in my original post...viewtopic.php?f=34&t=28032
please fix or at least give us a setting to customize.
