This is necessary for some grabs, which currently have no way of knowing when the pointer/keyboard focus has left a surface. For example, without this, a drag-and-drop grab can erroneously drop into a window that the cursor is no longer over. This is the plumbing needed to properly fix swaywm/sway#5220. The existing fix, swaywm/sway#5222, relies on every grab's `enter()` hook allowing a `NULL` surface. This is not guaranteed by the API and, in fact, is not the case for the xdg-shell popup grab and results in a crash when the cursor leaves a surface and does not immediately enter another one while a popup is open (#2161). This fix also adds an assertion to wlr_seat_pointer_notify_enter() that ensures it's never called with a `NULL` surface. This will make Sway crash much more until it fixes its usage of the API, so we should land this at the same time as a fix in Sway (which I haven't posted yet). |
