What does HackerNews think of xserver-SIXEL?
A X server implementation for SIXEL-featured terminals, based on @pelya's Xsdl kdrive server(https://github.com/pelya/xserver-xsdl)
That's not due to sixels. Check out the sixel nyan cat: https://github.com/hackerb9/sixvid
Look at the FPS indicator in the bottom. It was pointed to me in https://github.com/microsoft/Terminal/issues/448#issuecommen...
The issue may be in your code.
I think I have similar performance issues, as the glyph selection process could be more optimized.
Derasterized is mostly Jart work (who is best known here for her work on Cosmopolitan), we were mostly interested in quality.
Reducing the set of glyph to something that could benefit from optimizations could help.
> I really wish there was a decent pixel-framebuffer standard for terminals (with at least the same performance as ncurses)
Sixel performance is quite decent: personally, I can play videos in my terminal.
Try MPV on mintty: https://github.com/mpv-player/mpv/issues/2183
I have also played with a X server rendering over sixel, no performance issue: https://github.com/saitoha/xserver-SIXEL
When sixel support is added to Windows Terminal, I may update it, because it would be fun to have one tab to run stuff!
