Some loose, partially undocumented, but useful debugging methods found here and there in discussions, bug comments etc.

kwin_x11
export KWIN_USE_INTEL_SWAP_EVENT=0 # only affects intel IGPs export KWIN_EXPLICIT_SYNC=0 # most likely candidate on nvidia GPUs export KWIN_USE_BUFFER_AGE=0 # well, you tried, but hey ... ;-) kwin_x11 --replace &
gam_server
Sending a SIGUSR2 to running gam_server makes it dump its debugging information into /tmp/gamin_debug_*
kill -s SIGUSER $(pidof gam_server)
DBUS
DBUS can be followed using dbus-monitor, it can be lousy thou and hard to follow. Wireshark has dissector for dbus these days but it doesn't do that good job on it.
