The invention relates to the technical field of computer software communication, in particular to a layer display method, system and device and a medium. The method comprises the following steps: monitoring a layer display event of an application layer; when the layer display event is received, judging whether a target process corresponding to the layer display event has layer resource leakage in a system layer or not according to layer data carried by the layer display event; if the layer resources are leaked, clearing the layer resources corresponding to the layer display event in the system layer, and then displaying a layer corresponding to the layer display event; and if no layer resource is leaked, directly displaying a layer corresponding to the layer display event. According to the method and the device, the repeated creation of the layers can be effectively avoided, so that the problem of ghost shadow or layer superposition in application interface display caused by the repeated creation is eliminated; therefore, the display quality of the user interface is greatly improved, and better use experience is provided for the user.
