All I know about this crash was that it happened while rendering using the latest build:

latest.log

There isn't actually any crash in that log file. It just abruptly ends, it's also incomplete in that it's missing stuff at the start.

Do you have any info on how it "crashed" (i.e. did it really crash or was it just frozen and the tester killed it?) and whether there's a crash report somewhere (maybe it just didn't make it into the log) or a "hs_err_pid…" file (which would likely indicate a faulty graphics driver)?

@kareemAlramlawi Did you by any chance minimize the window while RM was rendering?
For complicated reasons I've never actually done that myself during development and someone reported a similar looking crash which is triggered by minimizing the window: #140

Also, in general please open a new issue unless you're certain your problem is the same as an existing one. And since we don't actually have the crash report for this one, we can't know if the issue reported by OP is the same as the one you're having (unless you're the person for whom OP has forwarded the logs, in that case you were right to post here).

ok sorry, I will delete them here and repost them there.

@Johni0702 hmm I never done that. I will tell you more details about it in #140 after around 7 hours.
