Created attachment 1265883 [details] FlatbedCursors Black Regular LH Description of problem: Pitivi does not work with custom cursor themes under Wayland Version-Release number of selected component (if applicable): pitivi-0.98-5.fc25.x86_64 Steps to Reproduce: 1. Set a custom cursor theme with gnome-tweak-tool. 2. Open Pitivi. Actual results: This log: Gdk-Message: Unable to load tcross from the cursor theme Traceback (most recent call last): File "/usr/bin/pitivi", line 144, in <module> _run_pitivi() File "/usr/bin/pitivi", line 128, in _run_pitivi from pitivi import application File "/usr/lib64/python3.5/site-packages/pitivi/application.py", line 34, in <module> from pitivi.mainwindow import MainWindow File "/usr/lib64/python3.5/site-packages/pitivi/mainwindow.py", line 47, in <module> from pitivi.timeline.timeline import TimelineContainer File "/usr/lib64/python3.5/site-packages/pitivi/timeline/timeline.py", line 34, in <module> from pitivi.timeline.elements import Clip File "/usr/lib64/python3.5/site-packages/pitivi/timeline/elements.py", line 31, in <module> from matplotlib.backends.backend_gtk3cairo import FigureCanvasGTK3Cairo as FigureCanvas File "/usr/lib64/python3.5/site-packages/matplotlib/backends/backend_gtk3cairo.py", line 6, in <module> from . import backend_gtk3 File "/usr/lib64/python3.5/site-packages/matplotlib/backends/backend_gtk3.py", line 61, in <module> cursors.SELECT_REGION : Gdk.Cursor.new(Gdk.CursorType.TCROSS), TypeError: constructor returned NULL Expected results: Pitivi working. Additional info: I attach my current custom cursor theme "Flatbed Cursors". Please, notice that I'm left handed. I got it from https://gnome-look.org, although it's no longer available. I haven't got this problem with any other application.
Solved. Somehow, this theme is incomplete. To solve this non-bug of Pitivi, change to the cursor theme installation directory and type: sudo cp cross tcross sudo cp hand2 hand1 Pitivi then will revive ;) Regards.
