Falkon using large amount of RAM over time
Open, HighPublic

Description

Over time Falkon 3.1 uses more and more memory, without ever releasing it. Closing the tabs will close QWE Processes but not make the main program free some memory.

What started with just ~120mb, after hours of usage Falkon is now allocating over 2gb of ram!

There's a memory leak or simply a build up over time. It's possible that Nvidia hardware acceleration makes Falkon use more memory. However, in my findings it's not more than 50-100mb extra ram being used.

Just as an example, Firefox uses around 250-500mb all the time. Compared to 2.2GB and growing of Falkon, it's WAY above normal.

I know Falkon went into 'maintenance mode' but it works nicely with the web and QtWebEngine is regularly updated.
If any dev care to look at this, it would be appreciated. It effectively makes this "lightweight" browser being a bloated behemoth over 1 day of usage.

I'm not sure why the bug report from 2019 was marked as "resolved fixed". It certainly was not. What that user experienced is exactly my findings as well.

This guy offered to help with a hint:

"For the devs using Visual C++ here is a hint that could help to solve this problem:
This extension https://www.deleaker.com helps A LOT to detect memory leaks, it could make things easier for yous."

Memory investigation is needed for sure, I hope someone could shed some light into this.
