BUG: F-16C TGP changes brightness when switching MFD pages

[Zolbat]

The TGP sometimes changes brightness (or maybe gain or contrast, but the image gets darker) when switching between MFD pages on that MFD.

It happens reliably (for me) when first starting a mission. It happens in TV, BHOT and WHOT modes.
This occurs in VR, 2D, offline and multiplayer.

Steps to reproduce:

| start Caucasus Free Flight
Main menu -> Instant Action -> F-16C Free Flight in Caucasus -> FLY

| TGP Contrast up
 Press right MFD "TGP" [RIGHT MFD OSB 12] -> press right MFD Contrast Up/increase

=> This increases visual brightness of the screen, pressing Contrast Up again decreases visual brightness , I'm pretty sure this is already a manifestation of the bug

| For obvious effect of the bug, increase contrast about 5 or 6 times total

Switch right MFD to some other page, i.e. HSD -> switch right MFD back to TGP

=> TGP is now noticably darker

Pressing Contrast up or down "resets" the brightness to the "correct" value again (pressing contrast increase brightens the image, pressing again darkens, as stated before)

 

Here's a short video demonstrating the problem.
Note the brightness decrease after switching to HSD and back to TGP once at the start of the video.

Before taking this video I did:
load free flight -> press contrast increase 1 time
