Shimeji on second monitor are black boxes

[ghost]

I am an Arch Linux user running XFCE. My monitor configuration is two 1680x1050 monitors, side by side.

Shimeji which appear on the second monitor are a black box no matter which monitor they walk onto. Shimeji which appear on the first monitor become a black box upon entering the second monitor.

Same ^^ and the shimeji are inside black boxes to begin with, but become black boxes when they have touched the second monitor

@GNUGradyn I'm on Manjaro using XFCE, so I guess it shouldn't be too different from you too. I don't have a second monitor with me to test the first issue right now, but as for the black boxes around Shimejis, it's easy to fix (if you're using XFCE default composition manager).
Go to Window Manager Tweaks, select the Compositor tab, and uncheck "Display Shadows under docked windows". That should do it !
