qtbase-opensource-src (5.15.2+dfsg-2) unstable; urgency=medium

  [ Alexander Volkov ]
  * Backport upstream patch xcb_screens_uaf.patch in order to fix
    use-after-free in the xcb plugin.

  [ Dmitry Shachnev ]
  * Build with libxcb-util-dev 0.4.0 which Debian now has.
    - Drop loosen_xcb-util_requirement.diff, no longer needed.
  * Bump Standards-Version to 4.5.1, no changes needed.
  * Upload to unstable.

  [ Lisandro Damián Nicanor Pérez Meyer ]
  * Build the experimental XCB native painting engine. This has been disabled
    as a default by upstream, but our X2Go users do really benefit from it if
    they export QT_XCB_NATIVE_PAINTING (Closes: #976274).
