So, my copy of Jedi Knight, acquired via GOG, worked just fine for the first seven levels - up to beating the first Dark Jedi (Yun).

But then at the start of level 8 (escaping from the building after defeating him), it crashes to desktop without ever loading the level (but after showing the cutscene to start the level - Kyle, with lightsabre, fighting off an ambush of stormtroopers with blasters.)

Worse still, when it does so, my text and icons are about 4 times their normal size and I have to reboot to get my desktop screen to appear normal again.

It seemed to work just fine up till then, under the options I was using. I just played it all through from level 3 to 7 without a hitch. My last quicksave is just before the end of level 6 - while it's technically legal to quick-save in a fight, it isn't really practical, and level 7 is the first boss fight.

(Also: If there was going to be a problem with one level that wasn't occurring in previous levels, I am surprised it was *here*, because in the original game, I thought I remember that the switch from CD1 to CD2 occurred one level later, at the start of level 9.)
