This is with Windows 10 Enterprise Version 1803. OS Build 17134.1069
It seems to be something specific to the computer, as it works fine on my laptop. I tried on all the available releases (0_2_8_4 through to 0_2_9_0), and seems to happen on all of them. Deleting the %appdata%/Roaming/remedybg directory, doesn't fix the issue either.
