@bigmuscle OK, I observed that glow effect. It's really weak... But it only appears on SOME windows. I took several screenshots for ref. There're glow effect on my Photo Viewer and Information Box of your tweak (Pic 1~2), but when I deselect it, the glow effect is gone (Pic 3). Either way, it doesn't help me distinguish the title from the dark background very clearly...(Maybe the glow effect can be stronger, like Win7?) But that glow effect doesn't appear on my Computer window (Pic 4~5). Is that just my problem? For those who have the same issue as I encounter (I saw a guy asking the same question in a previous post), please check whether you've installed Mactype or not. It's an open source hook forked from GDI++ which renders Windows fonts as beautiful as Mac does (Pic 6). I suppose there may have some incompatibilities between these two tweaks, but I'm not quite sure about that, as things remain the same after uninstalling the Mactype hook. P1 P2 P3 P4 P5 P6
