Title:
compiz rendering corruption in emacs
Status in compiz package in Ubuntu:
Confirmed
Bug description:
In Ubuntu 14.10, the Emacs GTK3 scrollbar does not render correctly:
it flickers or fails to update, sometimes randomly. I've spent a bit
of time debugging the problem: with plain X11 and twm, Emacs works
just fine. It's not the graphics driver: if I disable acceleration and
rely on pipelight, the scrollbar is still corrupted (albeit in a
different way, as if each call to gtk_range_draw just piles on the
previous one without erasing the background). Manually debugging the
rendering path in the cases where the scrollbar fails to update, the
cairo surface to which we render the scrollbar displays the correct
state (verified using cairo_surface_write_to_png), but this state
never makes it to the screen.
Emacs GTK rendering is somewhat unusual in that we use X11 calls to
draw the actual text *first*, then let GTK handle dealing with its own
expose events and drawing the scrollbar position. I suspect it's this
dual drawing model (which, while unusual, is completely legal) that's
confusing compiz.
