OpenGL Renderer Bugs

Forum rules
Please construct and post a simple demo whenever possible for all bug reports. Please provide links to everything.

If you can include a wad demonstrating the problem, please do so. Bug reports that include fully-constructed demos have a much better chance of being investigated in a timely manner than those that don't.

Please make a new topic for every bug. Don't combine multiple bugs into a single topic. Thanks!
