When opening the spidertron UI with active Schedule UI, the latter is wider than my 16:9 monitor. I assumed this was caused by the camera element, since nothing else used that much space, but removing the corresponding section of the gui code didn't fix the width issue.

The mod also caused spidertron inventory UIs to be moved to the left edge of the screen; even after removing the mod, in affected saves the UI keeps opening at that spot, while in other saves where spidertron patrols were never used, it opens normally in the middle of the screen.

What gui scale are you using? The game doesn’t properly support anything bigger than 100% for a 1080p monitor.

My UI scale is set to automatic (125%) on a 1440p monitor. The problem didn't appear to be a normal scaling issue - the schedule itself had the expected width, but the outermost frame (as well as the map view (camera) segment, when enabled) were far wider than normal.

This is with the camera frame commented out; removing that frame made no difference to the total width of the schedule section. https://imgur.com/a/0Iok3ii

Oh weird. My guess is that I'm using a particular frame style that is being overridden by some other mod. Can you send a list of all other mods you're using which you think might have something to do with a GUI in them perhaps?
