I'm finding KDE noticeably sluggish since the latest update, with kwin_x11 using quite a lot of resources. And "flip switch" Alt-Tab switching has gone away. (Graphics driver is nouveau.)
Check that you have Mesa-dri-nouveau installed. This contains the nouveau OpenGL driver, and got split out recently because it has severe problems (on some systems at least). See https://bugzilla.opensuse.org/show_bug.cgi?id=1005323 If it's not installed, Plasma would (have to) use Mesa's software OpenGL renderer, which would of course explain that it's "sluggish". And kwin would switch back to XRender compositing, which isn't supported by "Flip Switch" (it requires OpenGL).
