Crash in Big Sur

[buzz]

6-core Mac Mini - using latest stable StarTools version. Consistently crashes in contrast module, when I increase the precision parameter.

Stuck - cannot get past it. Is there a log file I can supply to help?

Apologies for the slight delay.
It's the first time I have heard of this.... Does this happen in both 1.8 and 1.7?
A crash log could indeed be helpful if this still happens in 1.8.

Thank you!

Hello there - it did it in the beta and stable versions. I'll reproduce and get a log file for the new year. You can take a well deserved break!

Hi Ivo, buzz,
I replicated this with ST 1.8.522 on macos 12.1. i mac end 2015 4 GHz Quad-Core Intel Core i7 and AMD Radeon R9 M390 2 GB. Here's what I found:
Increasing precision to 512x512 worked fine but not fast. Further increasing to 1024 x1024 made the cog wheel turn for about 30 sec before rendering finished: Finally increasing to 2048 x 2048 made the cog wheel stop again, but after like 1 min, MacOs reset to the login screen. Unfortunately this type of crash doesnt produce a report like an ST application crash would do. May it be we are looking at a GPU timeout or something here?
regards,
jochen

Thanks Jochen - that does indeed sound like a "catastrophic" driver crash outside of StarTools' control (an application should never be allowed to take down a user session like that...)
