Comment 1 Vlad Zahorodnii 2021-06-25 09:11:16 UTC

I think the problem is that the cursor texture is created without opengl context current.

Comment 2 Aleix Pol 2021-07-05 16:13:25 UTC

Still have the crash

Git commit 23129c09cebd5fc0220156934100d54f606d3b13 by Aleix Pol Gonzalez, on behalf of Aleix Pol.
Committed on 12/07/2021 at 13:15.
Pushed by apol into branch 'master'.

SceneOpenGL2::paintCursor make sure the OpenGL context is current

Instead of painting right away when Cursors::currentCursorChanged is
emitted, mark as dirty and call again when paintCursor is called.
