As I mentioned in other posts I’m not in love with R7 Mac jet, it feels very glitchy.
A file created in R6, saved to R7 gave me shading issues I did not have in R6.
While panning, zooming in-out, lines disappear and show up?
This happens in “Wireframe” mode and “Shaded” mode. Played with all possible settings, Rhino settings / Display Modes.
Bud it still recurs, even the whole color schema got messed up. Though it is temporary because after moving my Wacom pen/mouse it restores. Got some screen-shots.
NO it’s not my graphics card!
Mac Pro 2019
3,2 GHz 16-Core Intel Xeon W
192 GB 2666 MHz DDR4
AMD Radeon Pro Vega II 32 GB
MacOS Catalina 10.15.7
This is also a cures within other files with lines and 2D drawings.
