@sgunhouse Lucid Mode seems to be only for Opera Browser(or so I think) and not Opera GX. The equivalent of Lucid Mode in Opera GX is supposed to be RGX. Please, do tell me if you can find other solutions. Any help from anyone would be very nice, I use Opera GX as my primary browser and only it seems to be suffering from this problem.

@sgunhouse I'm sorry but I can't find such option in the settings. Also the colors look like they are somewhat normal after turning on the RGX. However it doesn't look as normal as it should. Is RGX the setting you are referring to? I always keep it off.

The colors look like they separate from where they should be. I had to take picture of display using camera because screenshot made it look normal. Below is the screenshot. I don't know what the problem is, when the laptop is restarted the problem goes away but occurs again after sometime.
