I haven't seen this problem nor searched the internet for more info on this topic, so I'm sorry if I'm answering too
impetuously. But talking about restricting texture sizes, this looks to me similar to a problem of some NVIDIA cards
(say: of my one) I have examined some time ago: when the fbConfig doesn't have its GLX_TEXTURE_2D_BIT_EXT set in
GLX_BIND_TO_TEXTURE_TARGETS_EXT, the power-of-two textures cause a BadMatch error in glXCreatePixmap instead of being
treated as rectangle ones as the GLX_EXT_tfp specification states. Couldn't this be related?
Mr. James Jones of NVIDIA said this will be fixed in the driver, so I didn't want to post any temporary workarounds
here. However, if anybody is interested, it's quite simple:
--- a/src/texture.c
+++ b/src/texture.c
@@ -236,6 +236,7 @@ bindPixmapToTexture (CompScreen *screen,
int attribs[] = {
GLX_TEXTURE_FORMAT_EXT, config->textureFormat,
GLX_MIPMAP_TEXTURE_EXT, config->mipmap,
+ GLX_TEXTURE_TARGET_EXT, GLX_TEXTURE_RECTANGLE_EXT,
None
};

It's pretty obvious if you look at the code. It avoids creating pixmaps
with certain widths even though that should work perfectly fine.

What patch is that? In case you're talking about this patch:
http://gandalfn.club.fr/ubuntu/compiz-patch/90-fix-no-border-window-shadow.patch
That patch has not been committed because it's not a fix. It's
a
workaround for an issue that no one have been able to track
down yet
afaik.
