The latest WIP (6.0.17269.9391, 9/26/2017) here is almost unusable. After about half an hour of work mouse panning and rotating is affected in either only zooming or only panning. Reboot is the only solution so far otherwise the entire computer becomes unstable.
Happened 4 time today already. I’m giving up and am going back to V5.
Also this WIP cannot printing to file Arctic view. I had my resolution set to Custom and 400 dpi which caused rhino to run print to file for several minutes and eventually freeze. Every single time I tried. Printing Display/Web Graphics with dpi set to standard 72 works fine.
