--- Comment #21 from danm...@gmail.com --- *SIGH* Well this bug has led to a new bug. I'm just going to post here since I have your attention :) I changed my app to use glxwindows to avoid the crash, and it turns out that this breaks glXUseXFont() :'( In detail: DRI_glXUseXFont() creates a Pixmap and X11 graphics context relative to the current glx context (see the line win = CC->currentDrawable; ) But now that I'm using glxwindows the currentDrawable isn't actually an XID for a Window, so the plain-old X11 subsystem refuses, and all subsequent operations fail. I get a stream of errors like: [17098] 7.810910: *** ERROR: xid=0x400010 req=53/0 err=9: X_CreatePixmap: BadDrawable (invalid Pixmap or Window parameter) [17098] 7.810919: *** ERROR: xid=0x4002cf req=55/0 err=9: X_CreateGC: BadDrawable (invalid Pixmap or Window parameter) [17098] 7.810923: *** ERROR: xid=0x4002cf req=54/0 err=4: X_FreePixmap: BadPixmap (invalid Pixmap parameter) [17098] 7.810926: *** ERROR: xid=0x400010 req=53/0 err=9: X_CreatePixmap: BadDrawable (invalid Pixmap or Window parameter) [17098] 7.810930: *** ERROR: xid=0x4002d1 req=70/0 err=9: X_PolyFillRectangle: BadDrawable (invalid Pixmap or Window parameter) [17098] 7.810934: *** ERROR: xid=0x4002d1 req=56/0 err=13: X_ChangeGC: BadGC (invalid GC parameter) (1000 or so more lines of errors deleted) So now I can either have text or I can have swap events, but not both! === To follow up on the whole "swap events reported but not actually generated" complaint: It looks like this was fixed in http://lists.x.org/archives/xorg-devel/2013-February/035449.html . I've added code to my app to detect this and work around it by falling back to not using swap events. === To follow up on the spec: the line of text "The mask field indicates which of the buffers in the drawable were swapped." Is referring to what must have been a deleted field. Probably want to remove this. -- You are receiving this mail because: You are the QA Contact for the bug.
