XVR-300 problems
Has anyone else seen problems with their XVR-300 cards?We have an Ultra 45 with two XVR-300s running a patched Solaris 10 11/06."doublewide mode" is enabled, as well as XineramaWe have seen a number of problems related to X drawing operations.Here is the first one.Because the problems appear to be unrelated, I'll post the other problems separately.
One of our apps draws a real time waveform.Random pixels of the same color as the waveform are being drawn at random intervals, but not very often. Maybe 20-40 seconds apart.Sometimes, parts of the waveform are missing.
I wrote a test program that reproduces the problem. 16 XDrawLine calls are performed every 100 milliseconds.The waveform wraps around, and an XClearArea is called prior to drawing the lines.In the actual app, a single XDrawSegments call replaces the individual XDrawLine calls, but the problem is the same.In comparison, an Ultra 45 with a pair of XVR-100s runs the test program without errors
The test program was written using dtbuilder.I can post this if necessary.
