So I was working on a CSS and this happened:
Sorry but you are not allowed to view spoiler contents.
So I replaced the CSS icons using Cl8 format and that's what may have caused it. So basically would I have to stick with CMPR? Or is there a way I can keep it Cl8 without it flickering?
I think you have to keep CMPR, dude... I tried RGB I don't remember which one, but I obtain a white background with my "WTF is happening?!" CSPs... They were switching their images with other things from the CSS... So, I think you should keep CMPR...
Just use CMPR. You don't lose much image information by switching to it anyway. Also, keep the MIP level to 1. Generally speaking, if the original files use a certain format you should use it. Otherwise, use CMPR to be safe.
