Another comparison. Lucid mode.
Lucid modes comp.jpg
So changing Lucid mode settings affects image quality. So if it was my drivers problem or something, then all other images were as ugly as the first one (with lucid mode off). The compromise is to use Lucid mode on with minimum settings (the bottom left image) but still it has a little sharp.
P.S. Updated to newest Opera 106.0.4998.41. So many updates already and this problem is still here
P.P.S. I tried clear Opera USB installation to new folder (no extensions, etc). The problem is there too.
