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)
