Slow SVG goban on safari (iPadOS)

Playing go on my ipad in safari. Extremely laggy when using custom stones and the new goban renderer. If I use the stone options OGS offers this doesn’t happen, with the exception of the anime stones which are also really laggy. When I switch to the old goban renderer there is no issue, custom stones are snappy too.

Something to do with <use> tags

Are you using custom SVG’s for your stones by chance? That’s the big difference between the Anime stone and the other stones, the anime stone is an SVG which Chromium is not caching correctly these days, where as it’s handling the image based stones just fine.

Yeah I was using SVGs. After reading your message I used GIMP to export them as png files, but I’m still seeing the same lagginess.

Interesting, ok good to know. Sounds like there’s some additional investigations needed.
