From b1bd0e2557ad7b151fa10a6735f9f14ca3b3a368 Mon Sep 17 00:00:00 2001 From: Guido Günther Date: Mon, 23 Apr 2018 16:16:47 +0200 Subject: layer-shell: Fix crash when cursor is intially outside any output On the X11 backend the cursor position might be outside the output window so no output is returned leading to the assert to trigger. Use sane fallback instead of crashing. --- rootston/layer_shell.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/rootston/layer_shell.c b/rootston/layer_shell.c index 836deb42..db0aeb59 100644 --- a/rootston/layer_shell.c +++ b/rootston/layer_shell.c @@ -395,8 +395,18 @@ void handle_layer_shell_surface(struct wl_listener *listener, void *data) { wlr_output_layout_output_at(desktop->layout, seat->cursor->cursor->x, seat->cursor->cursor->y); - assert(output); // And this one - layer_surface->output = output; + if (!output) { + wlr_log(L_ERROR, "Couldn't find output at (%.0f,%.0f)", + seat->cursor->cursor->x, + seat->cursor->cursor->y); + output = wlr_output_layout_get_center_output(desktop->layout); + } + if (output) { + layer_surface->output = output; + } else { + wlr_layer_surface_close(layer_surface); + return; + } } roots_surface->surface_commit.notify = handle_surface_commit; -- cgit v1.2.3
