Partial fix for minimap black tiles

[vfjpl]

[diath]

I have noticed that I have a more proper fix that doesn't completely remove the map view tile updates locally that I didn't push upstream, could you test if this fixes the issue?

From my tests solution proposed by @diath; is better, but I have a lot of changes on my fork that could also influence minimap behavior. Would be great to raise some awareness and push it forward, does not seem to be that hard
