Anki becomes a huge memory hog after increasing User Interface!

The memory usage for Anki increases ~3 to 4 after I increase the user interface from the default 100% to %170. I use Anki 2.135 on an M1 MacBook Pro, any help on a fix?

A doubling of screen size would mean 4x the memory taken up by display buffers. The toolkit Anki’s built on may not be handling it as efficiently as it could; you could try the current 2.1.50beta2-qt6 build to see if it fares any better.
