Created attachment 89399 [details] button comparison screenshot When comparing the current qtcurve stable version (1.8.18) with the latest git version (71ee6b071e), the bottom border of buttons does not render correctly in qt5. I have attached a comparison screenshot of the smplayer toolbar to show what I mean (stable version is top, git version is bottom).
I've narrowed this bug down to commit 3aeff5aae1e2d88045616dba4cf9dd789eb77652.
