Hello, I've been using aero glass happily and even donated to the effort. I really love the blurred transparency effect. Wanting that also in my taskbar, I downloaded the command line tool to change window's composition attributes and turned my taskbar blurred. Perfect, it looks awesome! BUT! For some reason I can't explain, when the taskbar blur is enabled, my Firefox browser stutters greatly. I've tested it on http://www.testufo.com/#test=frameratesand it only happens with the taskbar blurred. As soon as I return the taskbar to normal, the framerate goes back to being butter smooth at 144fps (I have a 144hz monitor). Even more strange is the fact that this happens only if my browser window is maximized! If it's just restored, even if almost fullscreen, this problem doesn't occur! EVEN MORE STRANGE is the fact that his only happens if I have my 2nd monitor is also activated. I can't for the life of me explain why this happens only explicitly if these 3 conditions meet: - taskbar is blurrred - browser window is maximized - 2nd monitor is active Anyone can give me an input on this, or perhaps a solution?
