From d643eb5c6fe50e7f1afffda0e8747a87f668a799 Mon Sep 17 00:00:00 2001 From: Sebastian Keller Date: Fri, 28 Apr 2023 12:20:11 +0200 Subject: [PATCH] frames: Disable XDND support on the frame window All X11 surfaces created by gtk4 claim to support XDND via the XdndAware property. This was leading some clients, e.g. Qt, to consider the frame window as drop target instead of the client window. Avoid this issue by removing the XdndAware property again after gtk has created the surface.
