Interesting, is each cell a separate item then? So assuming 3GHz cpu, we get 0.23*3e9/1600 = 431250 cycles per cell? That's a lot of work.
Here is a new screencast: https://www.dropbox.com/s/ywywr7dp5v8rfoz/Bildschirmaufnahme%202019-05-21%20um%2015.20.59.mov?dl=0
I optimized the whole thing a bit, so now a complete screen with layouting, hittesting, drawing takes about 28ms, that's 8x faster than before. Drawing is still around 10ms, layouting around 16ms, spatial index handling 2ms.
So this gives us 36 FPS which is IMO pretty good for a desktop app target. There might be some 2-3ms speed-up still possible but not worth the effort yet.
