Hi folks what is the progress on this bug?
I recently upgraded to fedora 11 and the bug is still present although in a different form. Now the caret doesn't blink and cannot be cleared. 

see the commentary in the abiword bugzilla here:

http://bugzilla.abisource.com/show_bug.cgi?id=12066

This basically makes compiz and compiz-fusion unusable.

We blink the caret by taking a snapshot of the screen pixmap, then draw the caret over that. It appears that taking this snapshot of the screen pixmap returns a solid black rectangle, rather than what was on the screen.

With compositing, the screen pixmap (or did you mean the root window? Anyway, same issue) is basically owned by the compositing manager, you can't rely on it having any specific contents. I'm not sure why you would need to read from there rather than from the Abiword window anyway.


P.S. Note that compiz bug tracking has moved to its own bugzilla.

I guess I wasn't clear. Here is the code we use to retrieve the contents of the gdkwindow we draw onto with abiword:
------------------------------------------------------------------
	UT_Rect* oldR = NULL;	
	cairo_save(m_cr);
	cairo_reset_clip(m_cr);
	m_vSaveRect.setNthItem(iIndx, new UT_Rect(r),&oldR);
	if(oldR) {
		delete oldR;
	}

	GdkPixbuf * oldC = NULL;
	UT_sint32 idx = _tduX(r.left);
	UT_sint32 idy = _tduY(r.top);
	UT_sint32 idw = _tduR(r.width);
	UT_sint32 idh = _tduR(r.height);
	cairo_surface_flush ( cairo_get_target(m_cr));

	GdkPixbuf * pix = gdk_pixbuf_get_from_drawable(NULL,
							_getDrawable(),
			        			   NULL,
						   idx, idy, 0, 0,
						   idw, idh);
	m_vSaveRectBuf.setNthItem(iIndx, pix, &oldC);

---------------------------------------------------------------------
Is the result of GdkPixbuf * pix = gdk_pixbuf_get_from_drawable(NULL,
							_getDrawable(),
			        			   NULL,
						   idx, idy, 0, 0,
						   idw, idh);
Now undefined in compiz?

Can you point me directly to where this bug should be reported? There is a maze of different components and products. Finally I'm not convinced this is not a driver bug. AbiWord works perfectly on an Nivida card with compiz.

I don't see a problem with that, assuming it's the right drawable, andgdk_pixbuf_get_from_drawable does what the name implies.

That's quite possible, I'm not seeing it with the free radeon driver either. But then it would need to be reported against the driver (not compiz, which is most likely not to blame), and with all the necessary information (log/config files, ...)

I've reported this bug to fedora with all the driver logs:

https://bugzilla.redhat.com/show_bug.cgi?id=478564

Do you know the driver bugzilla links? Is it Driver/i128, Driver/i740?

I can copy and paste all the info  into the correct bug entry.

I guess it's better after all to reassign this than to create a new report and lose the history...

Sounds like we're failing to flush something out in this config; so it definitely could be a driver bug.

This bug appears fixed in latest compiz+intel drivers on my Fedora 11 system. As of October 2nd, 2009.

Thanks for the update.
