Systems and methods are presented for screen painting updates on a client display to reflect changes in a remote server display. According to a method embodiment, an FBUR is sent from a virtual network computing (VNC) client through a network connection to the VNC server. The FBUR requests the VNC server to identify changes in a display of the VNC server. An FBU is received from the VNC server at the VNC client. The FBU identifies changes in the display of the VNC server. A screen painting algorithm implemented by the VNC client to update a display of the VNC client is dynamically modified based on a speed of the network connection. The display of the VNC client is updated using the screen painting algorithm.

Adaptive screen painting to enhance user perception during remote management sessions

Apparatus, systems, and methods may operate to send a window copy message including changed window identification information to a remote node when metadata associated with a changed foreground window at a local node has been cached, and otherwise, to locally cache the window metadata and send the window metadata and window pixel data to the remote node. When a preselected minimum bandwidth connection is not available between the local node and the remote node, additional operations may include sending a rectangle paint message including changed rectangle identification information to the remote node when rectangle metadata associated with a changed rectangle of a designated minimum size at the local node has been cached, and otherwise, to locally cache the rectangle metadata and send the rectangle metadata and rectangle pixel data to the remote node. Additional apparatus, systems, and methods are disclosed.
