Just upgraded to 8.5 and I'm getting hangs all over the place. 8.4 was fine.
If I try to open a previosuly existing project that has a bin that was left open in Frame View, avid will lock up with an AppHangB1 when it reads that bin.
I use the alt trick to open the project with the bins all closed, and the project does open successfully, but when I then open bins the clips *sometimes* look like the attached screencap.
Clips load and play fine in the monitor and timeline, there's just weirdness at startup and with bin display.
Both project and clips are dci 4k 24p with proxy off.
