+Subject: [PATCH] dix: Don't send touch end to clients that do async grab
+ without touches
+
+GTK3 menu widget creates a selection for touch and other events and
+after receiving touch events creates an async grab that excludes touch
+events. Unfortunately it relies on X server not sending the touch end
+event in order to function properly. Sending touch end event will cause
+it to think that the initiating touch ended and when it actually ends,
+the ButtonRelease event will make it think that the menu should be
+closed. As a result, the menu will be open only for the duration of the
+touch making it useless.
+
+This commit reverts f682e0563f736ed2c2c612ed575e05b6e3db945e.
+
+Fixes: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1255
