I've heard about the reflection, the boulder scene, etc. but the big question is: Does the brick still bounce in the sand after Indy leaves the well of souls?

I thought Indy's face looked really pixelated and distorted during the snake scene. In other words, regardless that I knew the glass was missing, if I didn't know that, I'd still think that scene looked like it had been altered.

I was surprised that they didn't digitally remove the piston thingie used to make the truck in the market tip over.

Yep, you can see the shadow of the bouncing brick if I remember correctly.

Why did this not get a digital fix too?

Things Fixed:
* The axle holding the boulder
* The cobra containment glass

Not Fixed:
* The log sticking out of the bottom of the truck
* The bouncing stone
* Belloq's fly
* The little seat that the stuntman sits on when hanging off the front of the truck.

This wasn't a mistake. In fact, it was a happy accident that was intentionally enhanced with the help of film editor Michael Kahn.

Why would they want to fix Belloq's fly
I am glad they didnt get FIX IT happy.

Yeah, that fly is still getting some decent residuals! What a performance!
