I have a user question on how to file a proper Debian bug report under certain circumstances.
Thank you for taking the care to find out what information is needed for a good bug report. Your specific use cases seem to involve non-free software (Steam games are, I assume, non-free in general, though there may be some exceptions) so that makes it particularly difficult to diagnose problems. If there are reproducible behaviours, it can be helpful to run the program under ‘strace’ and reproduce the behaviour, to get an extremely verbose log of system calls being made at the time when the behaviour occurs. When that is reproducible, it might be helpful to have two separate ‘strace’ log outputs: one from the environment where you don't get the buggy behaviour, one where you do.
Thank you for the suggestion, Ben. I really do appreciate it, and will try that as soon as I have some free time. I have seen videos of a similar effect in other Steam games ported to Linux, so I am actually concerned that this may be a regression in Mesa (which is free software) as Debian Stable's older version does not have the issue.  

I spend most of my time working on Windows, so debugging Linux will be something new. Thanks for helping me on that! If you don't mind, I'll post back on what I find so I can do this the right way.

Thanks again.
