So I've been troubleshooting for hours, trying to fix these lighting issues:
7D53C544F8E88C11FB04FC8F074E37B8E1E6C3B7
26B282F6A38E86EB4673A0A7988766D2BD48FAD0

I used Compile Pal due to its packing feature,
because I can't keep track of my content anymore for manual packing.
So I tried a compile inside hammer and the issues were gone.

Hammer Compile Settings: (It's an alpha so I need to compile fast)
VBSP: Normal
VVIS: Fast
VRAD: Fast

Compile Pal Settings:
VBSP: -game $game$ $vmfFile$
VVIS: -fast -game $game$ $vmfFile$
VRAD: -fast -game $game$ $vmfFile$
PACK: -game $game$ -bsp $bsp$ -bspZip $bspZip$ -keys $keys$
COPY: -copyDestination $mapCopyLocation$ -copySource $bsp$

I'd like to keep using Compile Pal for obvious reasons, so how do I fix these issues?

Your problem is fast VVIS and VRAD. Fast VVIS causes displacement edge shadows (as do hidden displacement faces adjacent to those edges, so check for those too). Either process on fast will cause the compiler to skimp out on lighting in general, so run those normally and see if your weird corner shadows persist.

Yeah but what I don't understand is when I compile in hammer with VVIS and VRAD on fast these issues don't exist, only when I compile with CP.

I don't think I can explain why your Hammer compiler isn't giving the same results because CompilePal is just a GUI for the same compile processes - so they should technically produce the same lighting issues with identical -fast settings. At the very least, CompilePal seems to be working as intended here.
