Summary: wl_data_device.start_drag called on the layer-shell
surface causes kwin to crash
Classification: Plasma
Product: kwin
Version: 6.3.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Wayland drag-and-drop
Assignee: kwin-bugs-n...@kde.org
Reporter: acct...@mail.rvvm.ing
Target Milestone: ---
SUMMARY
wl_data_device.start_drag causes crash when called on layer-shell surface. My
application opens fully transparent overlays on each of the outputs. That
overlays never receive keyboard focus and is on an overlay layer.
Application do following calls (WAYLAND_DEBUG=1):
[4247046.030] {Default Queue} -> wl_data_device#21.start_drag(nil,
wl_surface#24, wl_surface#2944, 2322)
[4247046.037] {Default Queue} -> wl_surface#5385.attach(nil, 0, 0)
[4247046.043] {Default Queue} -> wp_cursor_shape_device_v1#20.set_shape(2322,
16)
[4247048.940] {Default Queue} -> wl_surface#34.commit()
[4247051.742] {Default Queue} -> wl_surface#24.commit()
[4247063.969] {Default Queue} -> wl_surface#2944.attach(wl_buffer#2555, 0, 0)
[4247063.988] {Default Queue} -> wl_surface#2944.damage_buffer(0, 0,
2147483647, 2147483647)
[4247063.995] {Default Queue} ->
wl_surface#5385.set_input_region(wl_region#22)
[4247064.001] {Default Queue} -> wl_surface#2944.commit()
wl_surface#24 is a surface with the layer-shell role.
wl_surface#2944 is a surface without role used as drag-n-drop icon, on
.start_drag it doesn't have any buffers attached to it.
Right after wl_display_flush on my side compositor crashes.
STEPS TO REPRODUCE
1. Create surface with layer-shell role, keyboard focus disabled, layer =
overlay (Assume it's called wl_surface#1)
2. Create surface that will be used as drag-n-drop icon. (Assume it's called
wl_surface#2)
3. Start drag operation on wl_data_device, with origin as layer-shell surface
(wl_surface#1) and icon as wl_surface#2
4. Call wl_display_flush
OBSERVED RESULT
Compositor crashes
EXPECTED RESULT
Compositor processes requests from client and starts drag-n-drop operation (or
disconnects client in case of protocol violation)
