Good day @Bis!

Since 2013, player have seen black rectangles, when he look at Altis from the cockpit of my plane/helicopter

Example -

It arises only sometimes, for a certain period of time, then disappears, but then arises again and again to disappear again.
Please Note! I have tried probably > 50 Arma3 maps and have never seen such a glitch on any of them.
Out of all Arma3 maps, which I was seen, only Altis will have this black rectangles glitches, if the problem occurs only on Altis, it is likely an individual problem with this map.

Also I saw the same problem on the Altis video from other users on Youtube, so I'm pretty sure it's not my computer's problem. I change video drivers all the time.

Please try fix it!

Thank you in advance...
