I discovered that the issue was caused by OpenGL compositing crashing Kwin and thus KDE disabled OpenGL and all affects that relied on OpenGL compositing (including the Flip Switch task switcher effect I used) were disabled as well. Re-enabling OpenGL detection and then restarting KDE solved the issue. Thanks to everyone who responded.
