Slow QR code updates while typing, hanging the UI
While typing quickly when the code has grown somewhat large, the UI hangs. Note how in the video below (where I'm just banging randomly on the keyboard), both text entry and QR code stop updating until I briefly pause the typing. At the same time, Decoder is using 100% CPU.
I would expect that the encoding/rendering isn't this slow, and suspect that Decoder is somehow inefficient about it. If the encoding itself is indeed this expensive, it should at least not block the main thread.
This is using the 0.2.2 Flatpak.
