Yeah, I'm still trying to figure out what's causing this; once I do that, I'm fairly confident I can fix it. The problem is really that it seems very system-specific; I can't seem to replicate these "glow" issues on a ATI 4670 card (Windows XP, driver version 8.723). This makes it very difficult to debug, since I can't tell what's wrong, and I can't tell if I've fixed it
It might be helpful to me if people who are experiencing this issue could post the following:
1) Your system specs, including CPU, graphics card, driver version, operating system, and anything else you think might be relevant
2) A screenshot of the problem on your system, since it seems to look different for different people
3) A copy of your logfile
4) What conditions the problem does/doesn't happen under (e.g. does postprocessing on/off make a difference, or just realtime lighting? Does it only happen under certain gameplay conditions? Is it consistent, or does it seem to occur at random?)
Also, be sure that you're working from the most recent version of the 2.3 branch (since my first priority is getting that stable, that's where the changes will happen first).
I'll try to get this sorted out as quickly as possible; I appreciate everyone's patience with this.
