Did you run this in a memory debugger like Valgrind? In any case, I don't think make_unique() takes a size parameter, so the parameter is only used to init the created object. Just step through the code with a debugger to find out or study the docs at cppreference.com. BTW: I'd question your choice of using dynamica allocation like that when you could just build on vector.

If the code works as is, and you want a review of all of your code, you may want to check the help center to see if your question can be made on topic for Code Review. — Heretic Monkey 46 secs ago

@Vogel612 Did you feel any side affects from the first jab?
@Peilonrayz Will do.
@pacmaninbw just very minor ones right now, but it will probably take a bit
the tiniest headache, but quite some brainfog, slight nausea
OK, should only be a couple of days. The second one is worse.
yea, I'm expecting that
I had muscle aches from both shots, may have run a slight fever from the second shot.
Was really tired for 3 days after the second shot.

Core issue is that QDataStream &operator>>(QDataStream &stream, QPainterPath &path) basically iterates over all entries and does "ds >> type >> x >> y;" - it is a perfect example there OOP lead to a design which is very "data unfriendly": 3 different operators are called per entry with multiple checks included. The OGL implementation copies the whole data block-wise which is much more efficient. Maybe one could use readRawData to process data block-wise afterwards. However, this will mostlikely not pass code review as it defeats the built-in safeties of QDataStream. — Christian B. 6 secs ago
