Flashing screen on Tumbleweed with KDE plasma on Razer Blade Stealth

I have a Razer Blade Stealth, and it has an intel 620 graphics card. I have a problem where every few seconds it flashes…

It’s impossible to live with, and I really want to stay wiIth OpenSus if I can feel like I need to install the driver: https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.5

…but I don’t know how to go about it. There is a download for Fedora and Ubuntu, but otherwise, the only option seems to be “Intel® Graphics Update Tool v2.0.5 Source Code”, which I guess means compiling it somehow…

This would be outside my experience, and I’m not sure if it’s actually going to work.

Can anyone advise me please?
