Hi!
So we’ve been having the same issue for a while now and we had learned to live with it till one miraculous day we came across this setting in the editor preference.
Go to editor preference/ Level Editor- Viewport and the setting is called “Transform Widget Size adjustment” We were set at around -8 for some reason and it would really be bothersome. Setting it to -2 or -1 fixed the issue for us. We hope that will help another team out there.
Cheers!
