Comment 2 Noah Davis 2023-12-03 11:58:09 UTC

I see that Spectacle is being killed by the OOM killer and your PC specs don't look very high, so this is probably a duplicate of bug 475894.

*** This bug has been marked as a duplicate of bug 475894 ***

Comment 3 Noah Davis 2023-12-03 11:59:32 UTC

In your case, Spectacle probably doesn't eat all the RAM and freeze the system because you have the OOM killer.

Comment 4 Noah Davis 2023-12-03 12:39:03 UTC

Given that you only have 3.7 GiB of RAM, there's also a possibility that you didn't have enough RAM to start a recording even if there wasn't a bug. Spectacle usually needs 200-600 MiB of RAM while recording, depending on your system specs and what encoder is being used. Were you running anything RAM heavy like a web browser?

Comment 5 semlraug 2023-12-03 13:01:19 UTC

Thanks for your quick reply.

I have a browser open usually, indeed.

So my computer is not modern enough to run spectacle :-(

It depends. If you just want screenshots, you should have no problems. If you have more than 600 MiB of spare RAM before you start recording, you should also be able to record.

Comment 7 semlraug 2023-12-04 08:02:06 UTC

 Thank you for your help.

At EndeavorOS we've been looking at spectacle and testing it under qt6/Plasma6. I've been able to get my spectacle to run somewhat better by setting up a swap file.

There is however a bug that will crop up, where spectacle crashes, even on machines with 32gib memory. That bug will soon be reported separately here.

Thanks for all your hard work.

For now we should close this bug report, I think.
