670106 - OGL/GLX does not like image layers that are not xlib surfaces

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Florian Hänel [:heeen]]

For the checkerboard pattern I created a gfxImageSurface in layout/ipc/RenderFrameParent.cpp. This is used in an ImageLayerOGL to render the background for fennec.
On EGL, there is no problem, but GLX assumes all ImageLayers are Xlib surfaces, so creating a pixmap fails around here:

It leads to a crash as soon as you try to open a page.

Should we have an assertion if we then go on and test for pixmap?

Matt: please don't mark the bugs which you land on inbound fixed until the patch hits m-c, since it might get backed out before that, and we could potentially miss it because of the bug being marked as fixed.  Thanks!
