Opera Latest Version Memory Leak.

  • For roughly a week, Opera has been giving me lots of problems. I tried Opera GX but it's colors clash with every website that has a dark theme. Opera is by far my favorite browser and I want to continue using it if possible. But due to the colors of GX, I refuse to use it and if I can't get this fixed, I obviously won't be using an internet browser that uses up 60% of 16gb of RAM (over 8gb of ram for a net browser???)

    This problem does not happen with google chrome, mozilla firefox or microsoft edge. When Opera is open, my total memory shows incorrectly as well.

    In this picture, it shows Opera is only using 900mb of memory, however my memory usage is at 80%.

    In this image, Opera is open and my memory is not showing correctly. On the left pane, under memory, I'm using 12.9gb out of 15.9gb of RAM, however in the right pane, my in use RAM is only 5gb, my available ram is only 3gb. I would also like to note, yesterday, my available was 4.4 and my in use was 4.4, equaling 8.8gb, I have 2x 8gb sticks, so that means it's reading both sticks. Today, my total is only 8.1gb, but in the past, it has shown more than 1 stick worth. So I don't think my memory is the cause (also, considering it only happens with opera, does not happen with Opera GX or any other browser).

    After closing Opera, my usage drops to 22%, pretty much 60% change. 60% of 16gb is over 8gb that was just being used by Opera. Also note that even with only 8.1gb of ram, 900mb is NOT 60% of it. If I only had 8gb total ram and closed out an app using 900mb of ram, my ram usage should only drop by about 11%.

    And with closing Opera, my missing memory returns.

    Edit: Also note, this happens with any number of tabs open. 1 tab = 60% memory usage, 10 tabs = 60% usage. Just tested google chrome. 20 tabs open 20% ram usage. (60% for opera = 80% total, 20% for chrome = 48% total)

  • @saintgrimm Check Opera's task manager to see what is using that much RAM. Also check with all extensions disabled and with a clean Opera profile as instructed.

  • @saintgrimm i dunno if this will help.. but sounds like you prefer a dark theme on web pages.. if so Enable this flag.. copy and paste in the address bar


    even when vist 'n this forum i have a dark page.. *just say 'n..

    Note - i do not think this is an option for Opera GX but is for stable - beta - dev..

  • @nvmjustagirl How it's related to this topic?

  • @leocg it might help his memory leaks and he says he has color clashes..

    When his Opera is open, his total memory shows incorrectly.. may help to show right.. like i said i dunno if it will help..

    btw leo n e thing else

  • Is your Windows version 1909? If so, try closing your Discord program and see if the Opera memory problem reappears.

  • @blackbird71 @leocg Testing without discord. But it takes a good 6-8 hours to get up to 80% memory after I reopen Opera, I'll leave it open to tonight and know in the morning. If its back to 80% will look at details and see what I can find.

    Seems to slowly go up and my total memory slowly goes down. I'll check in an hour or 2 and see if my total is under 15.9.

  • Over night without discord, my total memory didn't go down, but Opera's memory usage still built over-night. I'm not sure how to check which Opera task is causing the most memory. They're ALL just called Opera Internet Browser. Except for Opera Crash-Reporter, and it's only using 1mb.

    The leak is slower without discord though. In 10 hours, my ram usage only went up 30%, compared to 60% in 8 hours before. Why does a specific version of windows cause problems between Opera and discord? And why did taking out discord make the leak only half as bad, but still existent?

    It's also still using more memory than it's claiming. When I checked on it and it was at 55% usage, task manager said Opera was using 1900mb of ram. My total ram was correct, 7 in use, 8.9 available. When I closed out of opera, it dropped to 21% ram usage. 1900mb is NOT 34% of 15.9gb, so it was obviously using more than 1900mb. Also note, 7 in use, 8.9 available is NOT 55% usage... But that's what task manager was telling me 😕

    I've been trying to figure out ways to keep Opera... If I turn the option on for it to bring pages back up when I reopen it, I guess I could just close out of Opera every few hours to avoid memory usage getting high. I'm not sure if it'd be wise to keep using if it causes a leak though.

    EDIT: here's a pic now. It hasn't really gotten a chance to start building yet, in fact it only says it's using 266mb, compared to the 1900 it claimed to be using when I closed it. Didn't think of taking a screen b4 closing.

    EDIT2: Can't upload the screenshot. Get a message "Error Something went wrong while parsing server response" when I add the photo to this post.......... Basically, it's the main then expanded (Opera Internet Browser (12)). It has 11 Opera Internet Browser's inside of it and 1 Opera Crash-Reporter. They all use varying amounts of memory, but I can't differentiate them from one another in any way.

  • @saintgrimm Like I said, Opera's task manager will show you all opened processes with RAM usage info, among others.
    Menu > Developer > Task Manager or Shift + Esc

  • @leocg Like you said? All you said is to check Opera task manager.... Never mentioned anything about this menu or developer mode. We never learned about a menu OR a developer mode for task manager in any of my IT classes, so I'm pretty confused as to what you're even talking about.

    I can't tell one "Opera Internet Browser" from the next, so even if one of them was using a huge amount of memory, I wouldn't be able to pinpoint what was actually using it other than Opera in general..

  • Just hit shift + esc in Opera to load its task manager and maximize the window.

  • @burnout426 Thank you, didn't realize Opera had it's own task manager. Kind of a weird concept to me, but guess it's pretty helpful when you actually know about it lol

    As of right now, the biggest user is GPU process, but it's only using 206,272kb. Guess I'll leave it open through today and report back after letting it build again.

  • @saintgrimm Yes, I said you to look at Opera's Task Manager, what clearly means a task manager that belongs to Opera, so a task manager inside Opera.

  • @saintgrimm in Windows task manager, enable the PID field so you can check there which Opera process is taking so much RAM and compare to the process ID in Opera's task manager.

  • @leocg And I had no idea anything like that existed.... You could try being helpful instead of acting so high and mighty, you know... Might make people enjoy interacting with you more. So far, the others posting here have been far more helpful and they don't seem to have such a big head about it either.

    Kinda to the point that I'd prefer no help at all than to read your condescending messages.

  • @saintgrimm You could have asked how to go to Opera's task manager if you didn't know.

  • @leocg Here we go again....

    I Did Not Know There Was Any Such Thing

    so naturally... I thought you must be talking about the only task manager I'm aware of....

  • @saintgrimm That's why I wrote Opera's.

  • @leocg Look dude, I don't want your help. You're being condescending and I'm not dealing with it. I won't be reading or replying to your comments any further.

    If anyone else on this forum would like to help and doesn't try to put people down over English not being their native tongue, and not berating people about not understanding the way you meant something, I welcome you to post!

  • Hi,

    The best you can do is to start a Clean Profile and check.
    Just Rename the current Profile folder.

    If it works,
    Then something is wrong: Cache, Extensions, or something else.

    If still happens,
    Then maybe it's a bug, try an older version and check.


    You can transport your current data to the new Profile and continue working, try to fix the current one or do both things to keep running and to find the cause.

    That way, you will learn about Important Profile files and what to do when facing issues.
