Summary
[cairo] crash with large accelerated canvas
arno.
Reported

Hi, when there is a large accelerated canvas (with a dimension larger than GL_MAX_RENDERBUFFER_SIZE) actually, webkit web process crashes by triggering the following cairo assertion: cairo-gl-surface.c:407: _cairo_gl_surface_create_scratch_for_texture: Assertion `width <= ctx->max_framebuffer_size && height <= ctx->max_framebuffer_size' failed. See testcase (GL_MAX_RENDERBUFFER_SIZE is 8192 on my system)

patch proposal We should see if this is fixable in Cairo. I'll check today.

I'm not able to get it to display properly, but it seems like Cairo no longer asserts in this case. Instead it creates an error surface, as one would expect. Given that I think this patch is no longer necessary. Arno, if you still think it is, feel free to respond and we can get this going again. I'm really sorry it took me so long to review this.
