Gray screen bug

[Sandy1942]

Three my friends had a problem in a patch 4.3 and they asked you to help. The bug appears only in single player (offline). After loading of quick mission or any other single mission on the screen there is a gray background on which there are ingame windows. 8657 8656
If night-mission, background black. If to switch to external view and back internal view gray/black background disappears, but appears again if to press any buttons of management of the review - a hat switch, NumPad buttons and some others. As a result of repeated manipulations with these buttons the background finally disappears and it is possible to play. But trouble also that emergence of a gray/black background is often accompanied by crash launcher and game stop work.
The bug appears on all planes. Online of this bug isn't present.

All three players use for survey of hat switch, NumPad buttons or mouse.

Sandy,

Do they have freetrack installed by any chance?
By the video it almost seems like is looking straight up when the gray square appears. There's a known issue with freetrack when you have it installed but not running where it makes the view jump.

Colander, many thanks!
Problem really in established freetrack. To my friends was helped by removal of this program.
