Flickering artifacts with EGLFS in RGBA8888 mode

XMLWordPrintable

      When I launch the QML application which contains an animations, then the screen sometimes flickers with an polygons artifacts on whole screen (please see attached screenshoot).

      I have reproduced this even with the standard demo QML application, called as "Samegame", e.g. from the /home/builder/Projects/qt5/qtdeclarative/examples/quick/demos/samegame/ path.

      Also it reprocuces with the Clocks QML application.

      This artifacts appeared only with the RGBA8888 mode (when QT_QPA_EGLFS_FORCE888 is enabled).

      Also I have added some debug output with QSG_INFO=1 (please, see in attachment too).
