From my occasional usage of Inkscape on a potato, I can say that it can be fairly heavy on the CPU when you do things, i.e. when it has to update the screen. E.g. for me it will frequently tear and be sluggish when scrolling. So maybe you're trying to do too much things at once or something is overloading the program (if your laptop = your SP3 however that shouldn't be an issue). Edit>Preferences>Rendering has a couple options regarding this behavior, so maybe that can help.

It’s not that Inkscape becomes unresponsive and freezes whenever I’m working on images because of performance issues. It just doesn’t want to recognize my mouse input consistently.

I try to move a shape with the Select tool but it doesn’t even want to select the shape to start with. Funnily enough, if I click and drag, it forms a selecting area. So Inkscape is recognizing that input. But if I try to move a selected shape by clicking and dragging, it doesn’t move. Instead, a new selecting area is made and I throw a fit.

I go to click something on any one of the toolbars and it doesn’t register unless I mash on some keyboard buttons or bring another window up and return back. The menu bar is the only thing I can actually click on that registers. Every other button and object (including the scroll bars) refuse to cooperate.

And this all starts even with a new and blank file.
