This autocomplete blinking/reset issue I witnessed during 1.4.20 EAPs while using AS Canaries is happening again with 1.4.30 RC on AS 2020.3.1 Canary 3, and it's making my job horrible, I think I'll roll back:

EDIT 1: Kept on happening after reverting to 1.4.21 🤔
EDIT 2: … but finally stopped happening after a while on 1.4.21 🤔
EDIT 3: Actually, it keeps on happening on 1.4.21 ðŸ˜
