-Subject: [PATCH] Client: Fix 100ms freeze when applications do not swap after
- deliverUpdateRequest
-
-[ChangeLog][QPA plugin] Fixed a 100 ms freeze that would occur if applications
-did not draw after receiving a deliverUpdateRequest().
-
-QtQuick does this at the start of animations. This should get rid of those
-backingstore warnings (and also remove a 100ms freeze before animations start
-in those instances).
-
-Fixes: QTBUG-76813
-Change-Id: Id366bf4a14f402fa44530ae46e7b66d9988c14f6
