Ahh, sorry for this...

BTW can we have a package using QT backend?(WITH_QT)
Kinda like the QT imshow window.

Comment by Antonio Rojas (arojas) - Saturday, 21 July 2018, 11:49 GMT
That would require a separate package, the qt and gtk backends are mutually exclusive.

Shall we fall back to gtk2 until upstreams fix this issue?
Comment by Cat (lasercat) - Thursday, 09 August 2018, 07:03 GMT
Or make a package opencv-gtk2 provides opencv and conflicts with opencv?
