When usin Mixxx in my x86 tablet (Lenovo Miix 2 8, Inter Atom baytrail) over Ubuntu 19.04 with gnome, neither the menus or the library sections respond to touch input, I cant load songs or enter the app settings. The transport, mixer and effects sections work as expected when touched, but the libray just get highligted but cant do anything with its elements.

See the attached video.

Update: On windows the touch works as expected in the library section. This bus seems to be specific to linux.

This video is more clear. This is over Manjaro Linux 19.

And this is on windows, where everything responds to touch.

(This sounds like an upstream QT bug if it works on windows but not linux)

Touch works fine in other Qt applications on Linux. There's a bug in Mixxx that is messing this up.
