Right now I don't see a problem on my system (Ubuntu 14.04 with hi dpi screeen). WHat should I be looking for?

[lasconic]

One of those buttons, when active, they looks bigger. http://musescore.org/node/116156
on macosx at least.

[Jojo-Schmitz]

Maybe Mac/Retina only? Depending on Qt Version?
And the dialogs fixed here are currently disabled I think-
Travis failure seems entirely unrelated

[MarcSabatella]

So all that is supposed to be needed to reproduce the problem is bring up Measure Properties and look at those buttons? They were fine for me before this most recent change, whether the buttons were active or not. Building again to make sure the most recent change didn't break anything for me.

Well, Measure Properties is still fine. I don't offhand see any problems with the harmony editor dialog either (I am running with "-e") or with the instrument window (whether invoked from the new score wizard or edit / instruments). Not sure what the toolbar editor is.
