Will try the 4.0 release on a fresh fedora 26 installation tomorrow.
On 64bits Debian the issue is now fixed!, thanks to the awesome team, no need of "alternatives".
congratulations @mrunion and @mmansilla, stick with Bootstrap Studio it's the best out there.
Bug is fixed! Using Bootstrap Studio 4.0.3 and Fedora 27 on HP 450 G4 notebook. Thanks!
