@gwen-dragon in CCC/Radeon settings for AMD graphics, there are Anti-Aliasing and Morphological filter settings that can be applied globally (if you want it as the default for your games). AMD seems to think it's a "game" so to speak that needs to be rendered differently. Best option is to set global settings to defaults then just adjust games individually each time instead of a global setting.alt text

Might be useful to prevent Vivaldi slowdown when open/loading multiple tabs together, & reduce rendering bottleneck problem for weaker PC.

@Gwen-Dragon I have filed a bug report and included all info I could think of. Thanks for your help.
