I mean, it could be. Intel integrated graphics don’t generally need additional drivers. That said, I have run KDE on stock Kubuntu and Debian and (outside of minor glitches, ofc) rarely had a problem.

From my experience, KDE can run well even on older computers. I have used KDE with only 2GB ram, a 10 year old dual-core Intel Celeron CPU, and an integrated GPU, and it runs rather well, if only a little laggy here and there. Of course, XFCE runs much better with that setup, though.

Just like a certain great philosopher said, “The sun is a deadly laser”
