I usually have 1-3 USS files in each UXML document. While working - adding new selectors, modifying them and saving in UI Builder window, i get following bugs:
sometimes selector jumps from one USS file to another
sometimes selector duplicates
sometimes it doesnt save changes
sometimes all of the above
So i always have to save every step, delete duplicates, move selectors, save again, try to modify it so that i see changes in window. Once it works it is ok, and everything is ok if i dont add new selector.
It is annoying, and i have these bugs in all Unity versions (on Windows and MacOS).
Did you report these bugs or are you assuming that they’re well known and a fix is being worked on? If you didn’t report them then I’d suggest doing that.
We cant fix what we dont know about
Please do file bug reports. If its something we already know about it will still show that multiple users are hitting the issue and it may even give us a better reproduction project to work with.
I’ve also had random duplication and movement of uss selectors in builder. Haven’t reported too since it was not critical to me and I didn’t know repro steps.
Same for me … Hard to say exactly how to reproduce steps, because it is so random. And also i never reported any bug, so i dont know how - so that it would be useful. I suppose it is not that hard, but usually i dont have time (because of the deadlines), and i always make workarounds and never look back
