Hi Tomasz, I remember (in our previous discussion) you said CrOS uses your own hwcomposer (proprietary?) so the story may be different. What we have tried is gbm_gralloc + drm_hwcomposer and I reported the issues here: https://lists.freedesktop.org/archives/dri-devel/2017-September/153580.html Sorry I didn't make more tests recently. I CC Mauro to comment. He should have made more tests with newer kernel and mesa. _______________________________________________ mesa-dev mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-dev
