dtgreene: I have a standard fullscreen monitor, and I get big black bars at the top and bottom of the screen on many games, including Lords of Xuliman and Freedom Planet. (Remember, not every monitor has ridiculously unbalanced proportions that are a pain for reading.)
My concern about bug fixes stems mainly from things like the Baldur's Gate 2 fixpack, which changes things like making certain spells not stack and doesn't provide a mechanism to pick and choose which fixes you want.
cogadh: That's not how true widescreen works. Actual widescreen support just adds the option for full screen resolutions that work on 4:3, 16:10 and 16:9 monitors. If you have games that do that differently, odds are you have your game configured wrong. Also, what world are you living in that doesn't have clear type and font scaling? Wide screen monitors, which are the standard, not the exception these days, are actually far easier to read than woefully outdated 4:3 monitors, if you bother to set them correctly (which all modern OSes do automatically now).
So you are concerned because a community mod changed things on a totally unrelated game in ways you didn't like? Therefore an official patch that actually fixes things should not be added to KotOR 2? That makes no sense whatsoever.
The problem of reading with widescreen isn't related to the font graphics, but rather to the fact that the eye has to keep moving back and forth on widescreen monitors. Also, I have no trouble reading text on my monitor (which is actually 5:4, by the way).
The thing with the fix concerns is related to past experiences. It is possible the fix only fixes game-breaking bugs (in other words, bugs that are likely to crash or softlock the game) and not things like abilities working too well, but I can't assume that an unknown (to me) patch for a game I have never played doesn't "fix" things it shouldn't.
Two examples of this I can think of: Wizardry 8's patch made pickpocketing almost useless, and a Daggerfall patch apparently reduced the weight a wagon could carry from 1,000 to 500.
