I've had this issue for a while but I didn't narrow it down to IR stuff until just today, I figured it was something to do with Journey Map. It seems that when playing near IR stock, the full screen map turns blue and none of the buttons show up. Picture below describes the issue better than I can. The HUD minimap doesn't seem to be affected.

While playing today the map was working fine, and then without me exiting the full screen, a train came past me and the screen turned blue. I waited until the train passed completely and after it was a few chunks away, the map was working totally fine again.

I play with a render distance of 32 chunks and if I go just a few chunks away from IR stock it seems to work just fine, so I don't think it's just any chunk with IR stock. Affected radius is only a few chunks, I can do more testing to get exact numbers if that helps. Tracks seem to have no effect.

Which journeymap version?

latest version, 5.5.2 for 1.12.2

Strangely enough my overall map works fine, but the minimap stopped working entirely for me with Immersive Railroading installed.

Journey map works fine for me with IR

@qwryzu can you PM me a copy of the pack and world to test with?

@qwryzu has this happened recently?

Can you make an interface for the machine to output items？

That comment has nothing to do with this issue...

I'm having the same issue also

V 1.12.2-5.5.4 journeymap
V1.12.2-5.5.5b6
V1.12.2-5.5.5b7
V 14.23.5.2838 forge
V1.6.1

Trains I used
Ge B40-8
UNU IR-113-LPR
UNU NY-212-MPR
UNU SC-126-HCR
UNU DS-123-MCR

Basically the trains ......

I just have the train sitting on the track and journeymap doesn't work in fullscreen

Fixed it u have to turn fast render off

I have had this exact same issue as well, currently on a server I'm working on.

I also have this Problem. But I think that is a Bug of JourneyMap, not of IR. Maybe it could have something to do with Optifine.
