The longpress function is currently called within the temperature ISR, which is bogus. Calling the longpress function at the wrong moment can corrupt the menu buffers. Move the call to the main loop by changing the logic slightly: - still sample the lcd buttons inside the temperature ISR, which keeps scrollong/pressing responsive, but... - set a flag to indicate that longpress has been triggered instead of calling the function directly - call the function on the next manage_inactivity run Combined with #3180 this removes _most_ unsafe operations out of the ISR which can happen during a normal run (max/mintemp warnings are still an exception).
