But when window is resized to full screen slower response and garbling the entire desktop still persists with CPU usage 100%. Acceptable performance is up to 60 to 70% of total screen size. Above about 50% of screen size the desktop garbling is noticed but goes off with desktop->refresh. This is for latest update. Thanks and Best regards R. S. Patil
