Question / Help Black screen issue on desktop

[biso]

As the title says, i cant get around this black screen issue when trying to record my games. Any help would be much appreciated!

Here's the log: https://obsproject.com/logs/VjYSwsccPbkUWLIm

Update: I tried just recording the screen and it works, if i try to record a specific window all i get is the black screen instead

I don't think window capture works with LoL.

Yes i figured out that i was trying to capture whole screen while lol was in windowed mode, silly me
