What's the problem?

[DreamMaoMao]

In the wlroots-next branch, moving the mouse cursor into the obs window will cause the cursor to disappear.

When using the same latest source code to build wlroots, there is no such problem in sway. This is a problem unique to dwl (wlroot-next). I would like to ask which section of code is the problem so that I can compare it with sway source code.

sway test:

Hm We change the cursor image in each call to wlr_cursor_set_xcursor and wlr_cursor_set_surface.

A good start to search would be motionnotify, setcursor and setcursorshape.

Also, when you say "not visible", do you mean that you cannot see the cursor on your screen, or is limited to only the recordings of obs?

it means thant the cursor cannot be saw on my screen

i try to force change obs some surface to xwayland suface by add some enviroment variable , the result is that the cursor can be saw on some xwayland surface in obs, and the cursor still cannot be saw on xdg surface in obs.

I see.

Can you try commenting these two lines in setup?

cursor_shape_mgr = wlr_cursor_shape_manager_v1_create(dpy, 1);
LISTEN_STATIC(&cursor_shape_mgr->events.request_set_shape, setcursorshape);

I commented these two lines of code,Problem solved!!

//cursor_shape_mgr = wlr_cursor_shape_manager_v1_create(dpy, 1);
//LISTEN_STATIC(&cursor_shape_mgr->events.request_set_shape, setcursorshape);

now it work .

I see...

I need to check sway code (removing those two lines is not a viable solution).

[DreamMaoMao]

When I looked at the hyprland source code I discovered the cause of this bug.This is due to some applications not getting the default system cursor theme. So I added an option in config.h to set the default cursor theme, which solves this problem.

[sevz17]

I see...

I think here are two problems:

• dwl uses the default XCursor theme
• The default XCursor theme does not uses the newer cursor naming spec

wlroots just merged a mr that could help with this, can you try again with the latest wlroots and dwl commits and with the two lines uncommented?

and also dwl can now be launched with -d option, can you use it and attach the stderr?
