weston transform examples not working
weston-transformed example should apply a transform to a surface, which is set by Left, Right and Space key. Similar, the
weston-fullscreen example should apply a rotation to the surface by pressing 't'.
On mutter 3.28.4 (Ubuntu 18.04) this kind of works (transformations are applied) but leaves artifacts after rotation (Left/Right key) in the area that is uncovered/damaged. On mutter 3.34.1 (on Arch Linux) the transformations are not applied anymore and the surface stays the same.
Was this functionality removed in newer versions to prevent glitches as seen in the old version?
