Player models

There are few desynchronization between the chest and legs:

• The chest remains at its height when a player/bot is crouching
• The legs are standing up after a player/bot is getting killed

Shader rendering

There are few issues with the high-resolution lightmap. The external lightmap is displaying way smaller than it should. You can particularly see this with alamo or elpaso. I get the same problem with the git version of ioquake3.

Third person spectating shadows

When spectating someone from the third person with r_forceSun activated (either 1 or 2). You can see a second shadow representing your character on the head of the player's shadow you are looking at.
