I submitted a fix to ppracer some time ago, which was merged. If you can name other applications, I suppose authors will be interested in patches as well. Tuxracer is not maintained though, so there is nowhere to send a patch.
FYI, all this was started by a non-conformant behaviour of the clamping mode on nvidia drivers, and people not testing with other drivers than the proprietary nvidia ones (which don't have this issue because of their buggy clamping behaviour). And now nvidia doesn't want to fix that behaviour, because that would expose those bugs (although some versions of the windows driver have a configuration checkbox to "enable conformant clamping behaviour").
