I tried posting this in bug reports but it wouldn’t let me.
I've been using alpha for about 2 months with no issue at all, no lag, nothing. It was perfect. However, a few days ago: When connecting a second display with alpha (Ghost is main display, macbook pro m1 is second display, both running alpha of course), the primary display does the normal show desktop thing that happens when connecting another display, but on the second display, it doesn’t show a black screen or anything it just gives the error code R-206. I've done graphics driver updates, reboots, left the shadow for a day and I've even done a full reset and the issue still occurs. Hopefully this can be fixed as I loved using the second display.
Other people in the discord have also reported this issue.
