I found the solution:
ROI has to be recalculated for negative x/y indicating using the
lower/right corner of the cursor buffer. Further, MDP5_LM_CURSOR_XY_SRC_Y
and MDP5_LM_CURSOR_XY_SRC_X mus be calculated for the hotspot:

Hi,
modesetting X11 driver may provide negative x/y cordinates in
mdp5_crtc_cursor_move(...) call when rotation is enabled.
Because of
static int mdp5_crtc_cursor_move(struct drm_crtc *crtc, int x, int y)
{
...
mdp5_crtc->cursor.x = x = max(x, 0);
mdp5_crtc->cursor.y = y = max(y, 0);
...
}
x/y
