<pre>Bumping this as I've run into this bug (feature?) while porting ANGLE to run on
GLX. When ANGLE is initialized we make the context current on a dummy PBuffer
created with {None} as attributes, which makes it a (0, 0)-sized Pbuffer.
Doing so on Mesa 10.5.9 on a HD Graphics 5500 causes the following to be
thrown:
X Error of failed request: BadValue (integer parameter out of range for
operation)
Major opcode of failed request: 53 (X_CreatePixmap)
It seems that the driver might be trying to back the PBuffer using a Pixmap of
the same size. The documentation of XCreatePixmap says that the width and
height should be non-zero or BadValue is generated.
Let me know if you need more information.</pre>
