I understand that it's completely normal to render at 60fps, that's why I was
hesitated to report this issue.
But I didn't expect this issue affects applications as well, like it had shown
in the testing video, I thought it was the desktop plasmashell only..
Osu! was set to unlimited framerates, but osu! and other applications are also
affected by this kwin render limitation.
Even if I set it to fullscreen, the issue persisted.
I only discovered this issue when I unplugged the 2nd display, I've been using
dual screen since the beginning.
I would love to see how plasma 6.1 works, since this issue is affecting stable
plasma 5.27 as well.
