Description Jan Bidler 2022-06-07 20:21:28 UTC

SUMMARY
When having a ton of room windows open (500+) NeoChat will start consuming a lot of memory and start freezing/crashing.


STEPS TO REPRODUCE
1. Start spamming the "Open room in new window" button a few hundred times.

OBSERVED RESULT
After about 250 or so new windows, neochat will start consuming about 5GB of RAM, and after a few more hundred windows will start to become unresponsive and in rare occasions crash. Needs to be killed via task manager, as it otherwise won't respond to close signals.

EXPECTED RESULT
Neither become unresponsive, nor crash

SOFTWARE/OS VERSIONS
Windows: 10 21H1
NeoChat Version: 22.04
KDE Frameworks Version: 5.94.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
I sadly achieved the crash only once, in all other circumstances, NC simply froze.
Terminal log doesn't seem to show anything useful, but i'll post it too just in case:

You're opening hundreds of windows, what did you expect, puppies? ;)
