🔴 OPEN BUG: HUD & MFDs missing after full-screen switch

[Krishty]

If a focus transition in full-screen mode triggers a lost D3D9 device, the HUD and MFDs disappear. The re-appear as soon as the simulation leaves paused mode.

Most likely,

1. any full-screen focus transition causes D3D9 to lose the device context;
2. lost devices lose all non-managed textures (like render targets);
3. therefore, all virtual screen textures are gone until the simulation renders them again.
