I frequently change the volume and brightness on my computer. Usually I modify them to more or less match my surrounding physical(!) environment. But there's this one annoying quirk with changing my volume and brightness.
When the brightness/volume indicator – I'm referring to this thing, by the way:
..fades out, my entire computer's frame rate just seems to drop. For example when I'm playing Minecraft and I'm changing my brightness or volume, the FPS drops down to about 10 from 110. YouTube videos also go from 60FPS to around a few frames per second.
Any idea what the cause of this is? It seems to be consistent across different Macs, too – I get the same issue on a new MacBook Pro.
