@leocg Had the issue on normal opera too but right now I'm on GX. There's nothing in particular, opera is around 3-4gb of memory and it's the highest of all. The next app is just 0,3gb.

I used to have 30 tabs open at a time and I faced 0 issues. Now I can have 10 open and it starts acting super slow. Checking the task manager, Opera is just taking up 5GB worth of memory. The lag is horrible. This can't be an issue with the computer, everything else works awesomely. How to fix this?
