If the cursor was grabbed the window the cursor moves over when it is
ungrabbed will recieve an EnterNotify event with the mode of
NotifyUngrab, unfortunatly some window manages such as i3 will ignore
this message and as such focus follows mouse will not function
correctly. This patch injects a normal EnterNotify to work around this
issue.
This fixes the following crash when attempt to toggle capture at the
right after closing the overlay:
zwp_pointer_constraints_v1@12: error 1: a pointer constraint with a wl_pointer of the same wl_seat is already on this surface
There is no action to be taken by the Looking Glass client, but a
handler needs to exist as certain other Wayland clients chooses to
send this message for copy-paste operations despite the fact it's
supposed to be used for drag-and-drop negotiation.
Certain window managers give us a scale before it gives us a size.
This commit makes the Wayland backend avoid passing a zero size to
wp_viewport_set_source, which is a protocol error.
This fixes an issue where the window position would be ignored if the
application was launched in full screen mode from the command line
causing the client to enter full screen on the wrong monitor in
multi-monitor configurations.
Under Wayland, if the mouse pointer is disconnected whilst captured
(like say via KVM switch), the waylandWarpPointer code will be called
but the pointer will be NULL. This results in the cryptic message:
error marshalling arguments for confine_pointer (signature noo?ou): null value passed for arg 2
Error marshalling request: Invalid argument
This patch adds a check on the wlWm.pointer pointer before attempting
to warp the pointer, and avoids the crash.
Many X11 window managers will present an application on their
taskbar as a combination of the application name and an icon
imagery pulled from the X-Property _NET_WM_ICON. Applications
built under frameworks such as Qt or GTK have this property
populated by the framework. This commit adds the Atom _NET_WM_ICON
and populates it with a 64x64 icon of Looking Glass.
For an unknwon reason when LG is on another desktop (hidden) and the
user switches to that desktop, the first attempt to grab the pointer
results in a GrabFrozen result. This adds some simple retry logic to
attempt again after a short (100ms) delay which seems to resolve the
issue.
