Mousepoll tries to solve the problem of not calling XQueryPointer () from individual plugins directly, but to centralize those calls, as they are blocking and can sometimes take up to (as tests showed here) 200 nanoseconds to complete. Nevertheless Mousepoll was a bad solution to a real problem - try to simply update the mousecursor position by calling XQueryPointer () in preparePaint (), which is called directly before painting, so each 16666 nanoseconds at 60fps and is only enabled via setFunctions () if the showmouse plugin (rulers or particles) is active.
