try kernel 5.3, I know it's flagged as release candidate still on stable branch but it works and is not end of life like the kernel you are running. once installed, your system will get updated to the released kernel 5.3 as and when the GNOME issues are dealt with that are delaying the next Stable branch update.

if you don't want to risk a release candidate kernel then try 4.19 LTS instead.

audio and video not synchronised ?

there is an Advanced setting for Pulseaudio Output Device ( pavucontrol -t 3 ) to adjust audio 'Latency offset'

No it's like a video drag when there's a lot of moving in the video

Thank you! Will see if that helps when I'm off work

switching kernel did not work. Its only glitching with videos everything else seems to be fine. Any other suggestions? It's driving me nuts, most of what I do on my laptop is stream

..not gonna lie .. one of the easiest checks is trying a different ISO.
(unless you have successfully run modern gnome on this machine .. try another DE from USB)

That said there are some manual amdgpu tweaks.. but you shouldnt really need TearFree in xorg, etc

But, maybe check these things out

you can uninstall tlp.
and set cpu governor to performance.
it will help in reducing lag.
