The latest version of Rider 2018.1 is pretty much unusable for me. The UI is constantly freezing every few seconds, just typing or clicking around, and everything feels so sluggish.
I had the same thing with its recent EAP, but assumed it would be fixed for the final release.
I've had to go back to 2017.3, which works fine. There is at least one other person in the office who is experiencing the same thing.
I'm on Windows 10.
