https://gitlab.gnome.org/GNOME/mutter/-/commit/7845e298b7cdca25fca4120319e9e6f95d585bb https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/5296 Upstream's final fix for X11 windows (Steam among them) becoming unclickable/inert after upgrading to 51-RC1: mutter!5296, "window/x11: Rebuild shape/input region when client size changes". Supersedes the author's earlier tentative workaround that this overlay previously carried. From 7845e298b7cdca25fca4120319e9e6f95d585bb4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonas=20=C3=85dahl?= Date: Thu, 3 Sep 2026 14:27:00 +0200 Subject: [PATCH] window/x11: Rebuild shape/input region when client size changes The input and shape gets intersected with the client size, which is set when a window is resized via 'meta_window_move_resize()'. If we for some reason postpone a window config when processing in when a window is initialized, it'd mean the regions will be intersected with an empty size, leaving them empty until they are explicitly updated. Address this by updating the regions every time their dependent size changes.
