Hi all, as promised some feedback on this matter...

I still do see tearing all over, so there's definitely no waiting for VSYNC, either in Qt5/EGLFS or the TI driver, but animations are smooth. >> You might also want to try the customcontext renderer from >> ssh://codereview.qt-project.org:29418/playground/scenegraph.git >> After building and doing make install there you should be able to use it >> by doing "export QMLSCENE_DEVICE=customcontext" or running with >> --device=customcontext I tried this code, too, although I had some problems adding Animators objects at the right spot in my QML files. It finally seems to work for me once Animations + animated objects are both from Animators. However, the result is not much better than with just "export QML_FORCE_THREADED_RENDERER=1". Tearing is even more obvious as the buffer swapping then seems to happen right in the middle of an animated texture covering the lower 50% of the display. >> If it's a timing issue you might also try >> QML_FIXED_ANIMATION_STEP=1 After setting this, animations are a bit quicker, but smoothness also wasn't better than with just "export QML_FORCE_THREADED_RENDERER=1". So, overall my remaining problem seems to be that buffers are not swapped with VSYNC. Any idea wether this is due to Qt5/EGLFS or rather the TI driver?
