gtk+ | Backend: Wayland | unspecified
Summary: Pixmap based cursors get surface destroyed after first
use
Classification: Platform
Product: gtk+
Version: unspecified
OS/Version: Mac OS
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: Backend: Wayland

GNOME version: ---
When a pixmap-based cursor is set as the current cursor, its wl_buffer goes
through the same general machinery than GdkWindow wl_buffers do, which does
call cairo_surface_destroy on buffer_release_callback(). These cursors don't
account for its only surface reference to be dropped elsewhere, and crashes
happen when the cursor gets reused (eg. setting another cursor, and that one
back).
I'm attaching a patch that adds a reference to the cairo surface before handing
the wl_buffer for rendering, so it behaves similarly to GdkWindows there.
