Subject: [PATCH xserver 19/24] xwayland: Also check
|
|
|
efa2d86 |
resolution-change-emulation when the xwl_window itself moves
|
|
|
efa2d86 |
|
|
|
efa2d86 |
The recent change to use the top-level non-window-manager Window drawable
|
|
|
efa2d86 |
coordinates from xwl_window_check_resolution_change_emulation() in
|
|
|
efa2d86 |
combination with only calling it on a resize when the top-level window
|
|
|
efa2d86 |
is moved breaks things with mutter/gnome-shell.
|
|
|
efa2d86 |
|
|
|
efa2d86 |
When fullscreening a X11 window, mutter moves its window-decoration Window
|
|
|
efa2d86 |
wrapping the top-level Window to the monitor's origin coordinates (e.g. 0x0)
|
|
|
efa2d86 |
last. This updates the top-level's drawable coordinates, but as the
|
|
|
efa2d86 |
actual MoveWindow is called on the wrapper Window and not on the toplevel
|
|
|
efa2d86 |
we do not call xwl_window_check_resolution_change_emulation() and we never
|
|
|
efa2d86 |
enable the viewport.
|
|
|
efa2d86 |
|
|
|
efa2d86 |
This commit fixes this by also calling
|
|
|
efa2d86 |
xwl_window_check_resolution_change_emulation() if the Window being moved
|
|
|
efa2d86 |
is an xwl_window itself.
