I have Opera 45.0 on a Windows 10 laptop with 8Gb of memory.
While I love Opera as a browser, it is eating the memory on this laptop to the extent that even File Explorer fails to open until I shut down Opera. Task Manager is showing nearly 100% memory usage in this scenario.
All is good then for a while but when I re-open Opera, eventually I end up with the same problem.
I'm only talking around 6 or 8 tabs open when this happens and none of them are doing anything stressful like playing video for example.
Without Opera running, memory usage is usually around 40%.
There seem to be a number of posts on Google about fixing the problem but none of them are applicable to Opera 45.0.
Check in Opera's Task Manager what is using so much memory.
Welcome to Opera's forums @Moapp!
For memory problems just rest around 7 hours +/- and keep away from tech devices for an hour before going to bed...
and keep a healthy live...
For Opera 45 Memory problems...
Do you use any extensions?
Try disable them, cleaning cache and also a clean profile and test it for a while, read the Back Up info too.
Leo's suggestion could be faster... for Opera xD
This has been an on and off problem for the last 4 months, Memory problems and then it's fixed for a few weeks and then comes back. During that time I get windows updates and sometimes opera updates. Needs to get fixed permanently or I'm going back to firefox.
Just kill GPU process if it's much on RAM.
Also check app CleanMem (Win10) if you will.
I have the same issue here, with a couple of tabs opened Opera is using more than 1Gb of RAM.
dev, beta or stable?
