Heya :D
So i finally figured out how to install Custom Cursors and decided to install this one :P
https://www.xfce-look.org/p/2347781

Sadly it only works with certain Applications like Firefox and such but for example uses the Stock Cursor on KeePassXC and STeam as well as some Video Games :(\

Does anyone by CHance have an Idea how to fix it? O.o
Or should i just try rebooting my Machine after applying the Cursor? >.>

Im on ARch Linux with Latest XFCE4 if that matters :P
Also Anyone got a Nyan Cat Cursor for Linux? >.>
Wouldve loved tp use this one but Cursors arent simple PNG Files you just apply to a Cursor it seems :(
