I'm not sure if this issue has been discussed, or if it's isolated to my hardware. I haven't experienced this on my work computer which is a dual Xeon workstation, but just my personal computer, which has a Ryzen 7 CPU.
Anyway, I have been able to replicate this issue in multiple scenes, both new files, or merged scenes. I have experienced the issue both on 1.7 and 1.7 HF2. When I have a scatter, either Corona or Forest Pack, my interactive render locks up my session of MAX constantly bringing up the round busy circle and MAX constantly will say not responding in the taskbar, then flash back to the IR, only to remain in a constant busy spin, where i'm unable to click in MAX or stop the IR. Then the cycle repeats. This forces me to close out of the session entirely. It's as if it's constantly restarting/parsing on loop but the duration of these not responding/busy cycles is the same regardless of the scene.
This issue only started within the last couple days and I haven't noticed anything that may be causing this. Am I the only one experiencing such issues or is this a common bug?
