[Bug 39371] Re: fadeout effect on displaying the logout dialog box looks bad

[Ryan Lortie]

I don't understand why lowering the brightness has to produce any strage effects.  I have a 24bit display and, for example, turning the bightness down on a truecolour image in GIMP would surely not produce strange effects like this.
