I installed Mojave 10.14.2 beta 4 on Friday (and now GA Mojave 10.14.2), and now when I use it to enter text on a website, I get beachballs like crazy every time I type in anything. No other application has this problem. I reinstalled Opera (both beta and general release) and also turned off extensions and it did not fix the problem. Any suggestions? Is anyone else experiencing this? Added- I also updated the Opera Browser to a newer version, and I still have that problem. I tried posting this on the Opera website and got no response, so I am hoping here there will be some ideas. I did NOT have the problem on beta 3, and did not update the Opera version until a few days after the beta 3 to beta 4 conversion.
