Bluescreen

Hi, I noticed, after the last openbeta update (2.8.0.32937) that at certain HSI magnification (5 and 10 NM) on the AMPCD I'm able to see the layout of airports in white. Is this a bug or intended? I'll attach screenshot. If I remove the map they also disappear. I tried in Nellis airbase on Nevada map and even if the map is not showed in the HSI, the airports are. Thanks in advance.
