Created attachment 50294 [details] Test program to recreate the mouse pointer flickering problem I wrote a program that utilizes the Multi-Pointer (MPX) feature of Xorg. The master mouse pointers blink every time I move one mouse pointer. The core mouse pointer doesn't blink. Test environment: - Two Keyboards and two Mice - Ubuntu 11.04, with Linux kernel version 2.6.38-10-generic-pae - X.org version 1.10.1 - Quadro 600 video card, with HWCursor = "true" and SWCursor = "false" - Nvidia driver 280.13 - Move the core mouse, the virtual master mouse pointer blinks NOTE: This problem can also be re-created with several other ATI video cards. I wonder whether this is a bug in the X server and what should I do different in my program to remove this problem. Attached is a short test program to re-create the problem. Please help. Thanks, Vu
This might be expected, since there is only one hardware cursor and the rest have to be emulated in software. Moving to Server/general.
