Opera Randomly jumps from using 10-20% CPU with 10 Tabs open to well over 30-60%, sometimes even 80% CPU Usage the second I use a single key, a single button, anything, the second I do literally anything, even so much as scroll or move my Cursor in Opera. All of those things immediately cause my CPU usage to spike to 50-60% minimum, and very using anything, may it be a Browser Game, YouTube or even just a website without videos, causes the CPU Usage to spike to the point where Opera GX alone is lagging out my PC. YouTube is way worse, watching a video alone lags my PC to the point where I cannot do anything and just having Opera GX run in the Background while I am on Discord causes my PC to randomly freeze.
Restarted PC, not one thing changed, in fact the Issue got even worse and while booting my PC was caught in a 20-30 second blackscreen before entering the windows login page. All of these issues occured after I used Opera GX for the first time after wiping my PC clean (Full on wipe, with every file on the PC deleted). Opera GX was also the only running, so the issue HAS to come from Opera.
Furthermore, using the CPU and RAM limit add-ons cause Opera to lag my PC to the point where not even Opera itself is usable. Not only that but Opera is consistently using higher amounts of RAM than before, jumping to 800 MB.
To add even more, ever since the installation and usage of Opera GX, my fans are running on maximum Speed. It is near impossible to switch between Programs and Windows using the Task Bar.
Opera GX Version
While editing the Picture, Opera GX caused my PC to lag out even harder and took the Picture 3 seconds to load (Picture normally loads within the fraction of a second), whereas editing the Picture is extremely laggy and takes a very long time (Also around 5-10 times as slow)
Example of the lowest CPU usage recorded in 2 minutes of Monitoring without doing anything in Opera GX
Due to Opera GX, Several Attempts were necessary to even open the file of the Picture/edit it, and even then, was only possible under extremely severe lag.
Example of Average CPU and RAM usage.
