Distorting colors in full screen mode.

[Xsvis]

Good time to all! Sorry for the bad English, I have to google translate.

I am having a problem with image distortion when I run OpenXcom in full screen mode. All colors disappear, only black and white with different shades remain. I tried to change the screen resolution in the game, crawled all the settings, updated the drivers for the video card, but still nothing helps.

In windowed mode, everything works fine, there are no distortions, but I am very uncomfortable playing with frames, they distract and do not allow me to fully immerse myself in the X-COM atmosphere. A few more details:

1. X-COM: UFO Defense version purchased from Steam.
2. Installed the latest version of OpenXcom 2021-03-29-1249 in the exe version.
3. The native resolution of the monitor is 1600x1200, the aspect ratio is 4: 3.
4. The game itself without OpenXcom runs in full screen without color distortion with a resolution of 640x480.

If you need any more details, I will promptly write. Please tell me how to get rid of this problem?

Can you show screenshot of this?

I tried to take screenshots, but they only came out as a black screen. I had to take a picture of the monitor. ))

Here's another example, a view of the main menu.

Did you try  display mode "borderless" in the video settings?

Thanks for the advice, I tried to set the "No frame" mode. The colors are normal, but a couple of centimeters of space disappear above and below.

In principle, this is tolerable, but still I would like to play in full screen mode. The most annoying thing is that before reinstalling Windows, I played in full screen and did not experience any problems with colors.

Thing is, the borderless mode should be indistinguishable from full screen mode, thus allowing just as good immersion.

I hate playing in windowed more as well, but full screen has always given me trouble, so I changed to borderless and I'm perfectly happy with it, it's 100% best of both worlds. Are you sure your resolution is correct?

Since windowed mode works fine, but full screen/borderless does not, that kind of sounds like a video driver issue.  I know you said you updated that, but you might need to downgrade one level (or check for further updates from vendor - trying to keep pace between vendor and MS updates is sometimes a challenge!).

Another thing is enable or disable OpenGL filters, as it use different code to output screen then result could be different too.
