Well, since this doesn't happen with my own slider widgets, I'd have to say AceGUI could be improved. If the slider has a step value of 1, for instance, it should be "smart" enough to round whatever value the underlying widget reports to the nearest integer before displaying that value in the GUI or passing it to the addon that "owns" the widget.

I'm not sure what "feels odd" about rounding the value yourself when the underlying Blizzard widget incorrectly provides a value that doesn't conform to the desired stepping. If the slider's step value is set to 1, it seems more "odd" to show users a value like 2.97 instead of just rounding it to 3 before displaying it or passing it off to callbacks. I've done this in my private slider widget library for years, as "not rounding to the step value while dragging" isn't a new behavior of the Blizzard slider widget. It's only really noticable in custom sliders, though, since the base Blizzard slider template doesn't actually display the value. I've noticed it for years in the "fade delay" and "fade duration" sliders in Bazooka's main config panel, for example.

Of course the Blizzard widget behavior "feels odd" -- it's a bug, and that's my whole point. Instead of sitting back and going "well, that's odd, idk what's up with that!", I'm saying you should just add a couple lines of code to work around it in your addon/library code so that the end result -- what users see and use -- doesn't "feel odd". Not sure how I can express that idea any more clearly, so if it's still unclear, I guess I give up...
