  • Opera uses the microprocessor on my Mac too intensively. I stopped using it for the reason that the screen display did not respond for a certain period of time (decreased responsiveness of the display). The situation returned to normal after I started using another browser. I am using the most recent version of Opera and macOS.

  • Facing a similar issue. Wanted solution for the same.

  • I'm using Opera 67.0.3575.137 and macOS 10.15.0 for 3 days with no problem so far.

    @tchang7 @sanjaykapoor When do you encounter the slowness? All the time, or when loading a web page, or scrolling a page once it's loaded? Is it only specific sites or any web page? Also do you have add-ons installed?

  • Hello,

    I use Opera 67.0.3575.115 and macOS 10.15.4.

    I have 20 tabs (20 websites) open, distributed on spaces 1 (13 sites) and 2 (7 sites). Space 2 sites are streaming (music, movies) or game (Twitch) sites, but I use them little or not, or only one at a time.

    UPDATE: I see that I was not using the most recent version (67.0.3575.137). The update has just been completed and I will see if this problem continues or not.

    Additional answer: In my case the problem was continuous. The installed extensions are Amazon Assistant for Opera, Opera ad blocker, DuckDuckGo for Opera, Install Chrome extensions, Share on Twitter, Video DownloaderHelper.

  • With the update to the most recent version of Opera (Version 67.0.3575.137) there is no longer any slowdown in the display.

    It is possible that in my case this slowdown was linked to a virus detected on my computer: Koiot.gen. I have not found any description of the effects of this virus.

    Another possible cause in my case is a bug experienced by several macOS Catalina users, inducing a kernel panic, which would be linked to the [Intel] GPU (Graphics Processing Unit): Constant Kernel Panics – userspace watchdog timeout: no successful checkins from
