Perhaps check anti-alias settings in /etc/profile.d/freetype.{,c}sh. The defaults in the freetype package do not have any settings enabled.

NVIDIA Lands Fix To Avoid High CPU Usage When Using The KDE Desktop
Written by Michael Larabel in KDE on 26 March 2019 at 05:38 AM EDT.

For nearly six years there has been a bug report about high CPU load when using the NVIDIA proprietary driver causing high CPU load when running the KDE desktop and making use of double buffering. This issue has been finally resolved.

Bug #322060 has finally been closed following a recent commit to KWin by NVIDIA engineer Erik Kurzinger -- this is the same developer working on the EGLStreams code for KDE/KWin, albeit in this case this bug fix is on the X.Org side and unrelated to that effort........

......This didn't end up being a NVIDIA driver issue itself but rather KWin making an incorrect assumption about GLX's swap buffers operation...........

Apparently, GNOME needs the same fix as mentioned above,

........The news coverage of NVIDIA figuring out the fix for KDE also happened to help GNOME developers in figuring out some long-standing similar troubles on their side. Canonical's prolific GNOME contributor, Daniel Van Vugt, has been looking at the NVIDIA high CPU usage bug and was able to confirm he already ended up having a previous but still open merge request that fixes the issue by accident.......
