ISSUE DESCRIPTION

Description of the issue: When loading into the sim and free flight I load the EFB to import simbrief plan. Before I touch anything the EFB changes from portrait to landscape consistantly. You cannot click on anything. If you then load into a flight the CPU is totally in the Red and Render is RED. FPS is down in single digits, something is completely slammed.
Sometimes it takes one or two restarts for it not to happen and everything runs fine. Although to note the efb opens in landscape mode and zoomed in when it never did this previously. This has happened in last two Beta versions

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)? It is Random, but usually at least one time when trying to load the game

did you by any change have any 3rd party addons installed for the EFB, for example NaviGraph or other ones? Removing them resolved my issue I had a descent calculator, Navigraph (simbrief and charts) as well as Bush Talk radio. Removed all of them for now has resolved it as it looks like
