+Subject: [PATCH] Fix Quick popup window positioning under X11
+
+If the popup window has the Qt::Dialog flag, some window managers may
+try to resize and move the popup after it becomes visible. This can lead
+to a blinking popup or even worse, it can cause a loop that continuously
+moves the popup window.
+
+Replace Qt::Tool flag with Qt::Popup to get rid of the Qt::Dialog flag
+but keep popup as popup.
+
+Note on Wayland Qt:Tool is xdg toplevel not a 'popup' neither 'grabbing
+popup' and it creates shell surface. This means it will get random
+position on the screen.
+
+Note this tricky issue as we already changed that several times both
+for widgets and quick due to different reasons (see 1390979a, 2f720836,
+58467ed19, 7e7dd2625, c56169f7a1)
