Indeed, with the newly attached patch the problem seems to go away. As a consequence of the patch, brightness control became ineffective in the game's option menu.
Of course, the patch deactivates the gamma setting. What seems harder is that the curves seems valid (too bright, but valid) so it's ok to accept them. The problem might be that some calculation with a value from somewhere else results in that bright curve. This means it should be a seperate bug (feel free to CC me when you create one)
