Heavy, and I didnt go for the true logo ;) but maybe it gives some ideas..

u/lewdev

I've never seen setLineDash before. Interesting.
u/Agnes

Why would they give us fillText and strokeText but not just text so we can add it to the path and do interesting stuff with it :(
u/cantelope

u/Agnes because like any path function, there are 2 ways to complete it, fill or stroke. text is just polygons

These donut things are great but are so slow on my computer. Anyone else have this problem?
u/cantelope

lewdev, there's known performance glitches with canvas in Firefox on Linux. Guessing that's your stack. Try Chromium?
u/tomxor

I actually always found Firefox canvas way faster than chrome, on Linux at least. Including this one, 30 FPS in chrome, but 60 FPS in Firefox, I got a new laptop this year so probably even slower in chrome on older computers.
u/tomxor

@cantelope You might be thinking of the subpixel aliasing issue on Firefox that appeared when they flipped hardware rendering on by default. That affected a lot of dweet rendering, I reported it a while back and it's been fixed in release since v128
u/cantelope

whatever causes the firefox+canvas+linux thing, somehow i always correctly guess the stack... whatever that means
u/lewdev

I was on win11 on my laptop, but it was slow on both Chrome & Firefox. It's smooth on my desktop Win11, which is much more powerful.
u/cantelope

well there you have it, bunk lappy
