Try squeezing the case lightly when it occurs to see if it goes away. The only real cure is resetting the connection which means you have to disassemble the upper case.
As for the squiggles try checking the cable connections for the screen behind the processor. The heat from the CPU may make one of the connections unstable. Just remove the grill, the keyboard pops up in the back, and remove the 6 screws on the aluminum plate to access them. You can contact me for further details if you need to.
