Make home screen icons round again, after Huawei update
I guess the device somehow lost my theme, and this ugly look is the fallback "no theme found" behaviour.

Anyway, I downloaded the "Legend" theme from this website, and used these instructions to apply it.

After I applied that theme (although I think any theme would do), I got a reasonable compromise: smaller icons and rounded-square borders.  This is certainly improvement.



Now I just need to reset the font and wallpaper, which I can do.

Still, if anyone knows how to get the really round icons again, I would like that.
