Yep can reproduce easily. Obvious fix is to remove the makeCurrent call from the BackingStore destructor, but that undoes a previous fix I made for surface resizing errors. I need to study the other QPAs to see what they do

qtubuntu (0.64+17.04.20170308-0ubuntu1) zesty; urgency=medium

  [ Gerry Boland ]
  * Implement QPlatformWindow::setMask and add support for special InputMethod
    window type
  * BackingStore: make current only if no existing context current (LP:
    #1665705)

  [ Albert Astals Cid ]
  * Implement UbuntuAppMenuTheme::createPlatformSystemTrayIcon
  * Register metatype used in queued invokeMethod
  * Make sure mMimeData doesn't point to already deleted memory
  * Initialize m_tag
