PC is stopped when walking along inclined wall or swimming along bank
See attached screenshots, it'll much clearer than just text explanations...
In Vivec, when walking up the sloping hallways, along the wall and aiming slightly INSIDE the wall, the PC is stopped when touching the wall instead of sliding against. When walking down in the same hallway, still aiming slightly inside the wall, the PC slides along the wall but not smoothly.
When swimming along a bank sloping enough so the PC can't walk up it, and when aiming slightly inside the bank, the PC is stopped when it touches the bank rather than sliding along it.
