Not always, but every few moves I notice the following:
When I place a stone, the board will show the new state of the board with my stone in position. It then briefly flashes back to the position just before I had put my stone down, then it returns to the current state of the board. I’ve had this happen for a few days now. This is very brief and occurs in a fraction of a second.
Is this in a demo board, analyse mode in a live/correspondence game or in a review etc?
It might help to reproduce it ![]()
I’ve noticed when playing live games on 9x9. Haven’t tried anything else recently
I was using a chromium browser on desktop. I can try on Firefox as well as mobile to tomorrow
This is an example of what I’m talking about:

I made a live unranked match to make this. Sorry if it doesn’t look too good, I’m not really sure how to screen record well + turn it into a gif.
I see this on my desktop using brave and firefox, I also see it on mobile using chrome and firefox. I use custom stones but, at least on chrome on mobile, I still see the same thing with the default stones.
That reminds me of what happens on another website between when the site is loaded and when your custom css is applied to the svg; is the svg getting refreshed?
