Created attachment 171747 [details] Screencast showing the issue using an AVD Android Viewer sometimes does not render the whole document properly, but for some or all tiles, a black area is shown instead. The best way to reproduce this for me was using the "Save As" feature: 1) open an existing document 2) use the "Save As" menu entry to save under a different name 3) check what the document looks like 4) if rendering is complete and OK, continue at step 2 until the issue occurs The attached screencast shows the issue. I could reproduce this pretty often on my x86 AVD, but only rarely on a "real" smartphone, a Samsung Galaxy A8. Android Viewer self-built from git master: Version: 7.2.0.0.alpha0+ Build ID: b43ab86df783
