Hi, could you try if starting awesome with the --no-argb flag fixes this?
First: "Why I think that this is not a bug in awesome" The systray is implemented as windows. The systray provider (awesome in this case) only places these windows, but it does not draw them. Since in X11 a window cannot be at multiple places at once, awesome cannot actually cause this. Second: "Why I suggest --no-argb" I do this for all bugs involving rendering issues. If you want, you can check if the fix for [1], which seems to be [2], makes your issue go away.
