This is with the latest drm, mesa, xorg, driver ... ports but happened also with all versions since January (didn't try earlier stuff). Sometimes there are 1-2 minutes between these messages and sometimes it takes up to 1 hour. It almost never happens under normal desktop work (fvwm2 with a lot of xterms) but as soon as xlockmore with its GL stuff kicks in the messages appear. I didn't find a lot about it on the web -- just some linux posts where the problem appears to be fixed. Anyone else seeing this? -Andre
