Comment 1 fanzhuyifan 2024-03-12 15:45:42 UTC 
Can reproduce the high memory usage part, but given that it doesn't grow without bound, and instead stabilizes around 2Gb, this probably isn't a leak but just high memory usage.

Sounds like https://bugreports.qt.io/browse/QTBUG-120007
Comment 3 Nate Graham 2024-03-13 21:47:50 UTC 
That was supposedly fixed in Qt 6.7 though, and Yifan is using that but can still reproduce the issue.

Comment 5 Antti Savolainen 2024-03-31 12:51:15 UTC 
Still an issue. I already froze my PC once for going OOM. The memory reservation also lags the application.
Here's a demonstrative video: https://youtu.be/HtzUjkowq9o
Comment 6 Antti Savolainen 2024-03-31 12:53:05 UTC 
The window size seems to affect how much memory the application is using. At minimum size it's barely noticeable but at full screen it can hog all of the RAM.

*** Bug 485241 has been marked as a duplicate of this bug. ***
Comment 8 Antti Savolainen 2024-04-13 10:51:32 UTC 
Was this fixed in Qt 6.7? I'm no longer able to reproduce.
Comment 9 Nate Graham 2024-04-13 21:52:02 UTC 
The upstream bug is marked as fixed in Qt 6.7, so it looks like it! Thanks for following up.
