Hi @ezacarias! Does this bug still happen to you? Could you please provide some of these details: How much RAM do you have? Is it running low when Opera slows down? Do you use an antivirus software? If yes, which one? Is this a laptop computer? What kind of graphic card it uses? Which version of drivers? Was your internet connection stable when the bug occured? Is this still happening in the newer versions of Opera? Cheers!
