Created attachment 50294 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.
- 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.
