Not sure if this is a bug or I'm just doing it wrong, but I've been having an issue which is that the Set BACKGROUNDIMAGE command seems to always fade despite using "nofade".
The weird thing is that I couldn't get the unexpected fading to happen in either a Windows Sandbox or a fresh virtual machine I also tested it in, even when I backup and restore my entire config into the Sandbox & VM. However, that might be from a graphical limitation in Sandboxes/VMs in general, because I couldn't even get it to fade at all, even intentionally, in the virtual machines. So it's possible it would fade if it could.
Here's a video
I seem to recall first noticing this problem around the update when the 'local' background image option was added. I thought it was something I was doing but I'm not sure now. I'm pretty sure nofade worked before.
Here's an example of a command I'd use:
Set BACKGROUNDIMAGE filedisplay:C:\Test\Left-Gray-Arrow.png BACKGROUNDIMAGEOPTS=local,center,nofade
To Reset:
Set BACKGROUNDIMAGE="all:" BACKGROUNDIMAGEOPTS=reset,local,nofade
If the commands are correct but the behavior can't be reproduced, I can do more testing to see if more options affect it.
Fixed now.
