Colors Washed out
Every time I run Scrcpy the colors on the screen seems to be washed out even my screen brightness is at the maximum. This screenshot is from the app itself. The box in the middle is supposed to be full white but it's kinda gray as if the brightness was low. Maybe it's something simple to fix but I couldn't find anything related on the issues page. Thanks!
Is it the same with:
adb shell screenrecord /sdcard/file.mp4
adb pull /sdcard/file.mp4
vlc file.mp4
?
I had this happen because of a blue light filter app. In addition to filtering out a percentage of blue light to affect the color temperature, it allows dimming. (I like using this, because even with Android dimmed to its lowest setting, I'd prefer it to be dimmer if I'm using it with the lights off, to not disturb my wife.) The Android doesn't have these functions for it to use, so it has to simulate them by doing something like a transparent overlay on top. So, when I first used scrcpy, it displayed as a different color temperature and dimmer, because the white pixels on the screen that it was copying were in fact not 100% white.
Our eyes adjust to what we perceive as the whitepoint. If you've ever had an app like this, see if it's still running. Even if looking at the actual phone looks like it's not affecting it.
Well.. turns out the "problem" was on my phone. The same thing would happen when taking a screenshot. The screenshot itself would be darker than what was on the screen. While looking for a way to solve this, I came across a post on reddit saying that if you set your phone to automatic brightness this might happen. So I just unchecked this option, restarted the phone and it was solved. I'm on a Xiomi Mi9 SE by the way. At least now we know what to do in case this happens again. Thanks!
I noticed a quirk while watching Youtube. When I press the spacebar while watching a video, a grey overlay appears on the screen and on the phone as well. This effect vanishes when i close and reopen the video. I've attached a video here, you can see the screen greying out when i press the spacebar.

I have noticed that the problem is due to dark mode being on at least in Xiaomi devices, the moment you turn off dark mode this it's solved
Can confirm it's an Xiaomi issue with dark mode, @rom1v is this possible to be fixed? If you are too busy and you can give me an direction of where I can find the issue in the code base I could try to fix it
@rom1v is this possible to be fixed?
No idea.
Does it also happen with screenrecord? https://github.com/Genymobile/scrcpy/issues/1868#issuecomment-719095574

Yes, it does happen on recording. @rom1v
