Have you tried Pyglet 1.2 alpha1 or the repository code? Yes What steps will reproduce the problem? 1. Run the attached example or 1. Create multiple vertex lists in the same domain 2. Resize any vertex list from size 'n' to 0 (except the first vertex list) 3. The first 'n' vertices in the domain are overwritten Error only in graphical data, no traceback or error message. Bug was prevented by changing the following lines in the VertexList resize method in vertexdomain.py: old = attribute.get_region(attribute.buffer, self.start, self.count) new = attribute.get_region(attribute.buffer, new_start, self.count) to: old = attribute.get_region(attribute.buffer, self.start, min(count, self.count)) new = attribute.get_region(attribute.buffer, new_start, min(count, self.count)) I don't know if this change is at all safe or appropriate, but it fixes the bug as demonstrated in the attached example code Paste in the output of `python -m
