When on ground start moving it glitches in and out. When in air and zoom in/out or pan anywhere it becomes unusable. Sometimes it will clear up if re-centered on aircraft and get back to starting zoom position.
Same issue with Pimax Crystal Light. If the map is centered on the aircraft and there is no active flight plan, it seems to work Ok and I can zoom in or out, but as soon as you pan the map around, it glitches like crazy. When a flight plan is active, the map doesn’t pan or zoom at all, you just end up dragging the flight plan path around and zooming only affects the size of the flight plan path.
At least the issue with the ATC window resetting its position every time it was closed and reopened has been fixed.
I confirm the same random flashing issue with EFB.
Another issue is with field spraying, I fly helis and zoom in with EFB to keep track of the area sprayed and quality. However, it shrinks the area sprayed. If you use the mouse wheel it reverts to normal until some moments later it will shrink the sprayed area. By sprayed area I mean the colorful area on the map that shows the spraying.
