+Subject: [PATCH] Prevent duplicate session name.
+
+Several desktop sessions (e.g. KDE Plasma) already include the string " (Wayland)" in the session name. When this happens, the session name displayed to the user is "Plasma (Wayland) (Wayland)". This change makes it so that only "Plasma (Wayland)" will be displayed.

+Subject: disable automatic portal launching
+
+in Qt6 (and the KDE patch collection for Qt 5) genericunixservices will
+internally attempt to probe the portal tech early on in the app life
+cycle. this causes the protal system to launch app and then crash
+because we aren't actually providing a fully functional session. instead
+opt out of this altogether
+

+Subject: Enable QSurfaceFormat::ResetNotification on new Qt
+
+This fixes graphical glitches on nvidia after VT switching.
+
+It's opt-in as it requires code paths to handle glGetError differently.
+The version comparison is because my early implementations missed a code
+path. This was fixed in 5.12.2, but we may as well play safe
