Can I hide floating messages like "Destination full" on the shots like the below?

https://mapshot.2238club.org/map-ee1780f4/index.html?x=201.4&y=-254.8&z=1.3

Is it one of the train message when they get stuck, have no path or similar? I'm not sure if it is possible to hide them. Mapshot is using the take_screenshot API (https://lua-api.factorio.com/latest/LuaGameScript.html#LuaGameScript.take_screenshot), which does not really have anything specific to it.
Maybe deactivating show_entity_info would remove it, but it would have other impact; you can try that by editing slightly the mod here: https://github.com/Palats/mapshot/blob/master/mod/control.lua#L250 (replacing true by false). If that works well enough, it should be possible then to make it a proper option (instead of having to edit the code).

just look at the trains while starting the command, when the floating text is gone press enter, viola no floating text in the map

Lol, good luck on a save with 1000+ trains

Could the mod flip all the trains into manual mode before taking the screenshot?

The message is synconized on all trains
