Well, I recommend lowering the brightness of your screen or messing with the contrast settings to dull the general color of your monitor if you're getting visual problems.

So far in six-plus years SL2 has always been 'white texted', it's weird such problems are coming now. I don't personally have 'that', but, maybe the fact the chat scrolls a lot faster than before (due to bigger text size, icons, etc.) and we're no longer stuck to the 'dark blue background, white text' which fit like a glove, is making even me feel a little worn out mentally.

Food for thought!
