[Digikam-users] Perspective Adjustment tool in digiKam 5 Issue

[Philip Johnsson]

Dmitri,

Are you using a nvidia video card as I do? I just tested to change to the
open source nouveau driver instead and with this driver the preview drawing
with perspective adjustment doesn't lag like it do with the nvidia
propriety driver. Too bad the nouveau isn't as good in other regards that I
want to use it but I guess that suggests that the problem is related to
QT5, OpenGL and/or video drivers and not Digikam itself.

/Philip
