Those are memory leaks dude, that's just bad programming
Whatever they may be, it is what it is. As an end user I use binaries, I don't reverse engineer, and recompile software I use.
As a side note I discovered the browser leak issue is caused when using D3D9 for ANGLE, its by far the fastest, but it has this leak problem so that particular leak is resolved by switching to a different graphics API, but not much I can do about games using lots of VRAM, it is what it is there.
Games that use high quality textures however will need a lot of VRAM leak or not.
I do mod games that are moddable to enhance the experience, this nearly always involves better higher quality textures as well.
