This is a bit of a bug report.
As most people are probably aware, if there are too many planes around you, the ones further away show as white squares. When viewed from the ground, the white square of a landing plane sometimes become invisible because of the sky background, and for some reason, the text showing callsign/username does not show. The only way to actually see the plane is the map.
The exact bug is that the white square blends into the background in certain conditions. A different color might be needed.
Is there any fix for this?
