https://ossia.io uses widgets and qgraphicsscene for the main UI rendering and Qt rhi for the GPU pipeline, and it's performing well enough for our use-cases - I was working on it on a 1080p screen on a Pi4 recently and it certainly felt much much faster and responsive than chrome on the same hardware.

  Demonstration app for my lightning talk at QtDevCon22 - Handling Large Amount of Text in QML

Hi! Thanks for your interest. I've been doing some thinking in the last couple of days and decided to close source the code for Plume.[1] I'm going to update the website now. I've contributed here[2] for text selection between different blocks if you want to take a look.

Of course, you'll have to implement yourself editing between blocks, undo & redo, copy & paste, etc. For me, a big challenge was to synchronize between the state of underlying plain text and the rendered HTML since Qt's conversion is incredibly inconsistent, it requires some annoying small modifications each time.

BTW, there's a high chance I'll open source Plume in the future. I don't fully trust any non-open source app without a transparent build process. But only after I'm sure I figure out a sustainable monetization source.
