Why do I see artifacts around my Text and Boxes, when using the OSD graphics controller in 3 Channel Mode?

解决方案

This is due to the third channel asserting one cycle earlier than the first two channels.

This problem only affects the 3 channel interface, and is addressed in the next release of the Video On Screen Display IP.

This problem has also been fixed in the latest version of the Video On Screen Display.

See (Xilinx Answer 33257) for a detailed list of LogiCORE IP Video On Screen Display Release Notes and Known Issues.
