Having will issues are these things typical of a hackintosh?

This is my first hackintosh previously I used Mac hardware.

I'm having some weird software issues and am not sure if things like this are typical of a hackintosh as I've never experienced them over many years with Mac hardware.

When opening a PDF preview becomes unresponsive and I have to quit the app about 90 percent of the time. Quick look also will not work on preview.

Random characters will not display in Firefox and randomly images will not loads on certain sites but they work on Safari.

When I click shutdown it will restart instead.

I did not have any of these problems a month ago.

I'm just wondering if this is party of maintaining a hackintosh or if this is a one of weird issue.

I'm on 10.14.1
