Tried opening a .odg file in Draw and had black shapes covering the artwork. It looks fine in the “recent files” preview and print preview but in the editing window everything of interest is covered in black blobs.
Tried in 6.2 and 6.3 on Win10 64-bit. Tried saving as ODF and re-opening, same problem. Tried toggling OpenGL, hardware exceleration off.
Only workaround so far was importing the PDF version and editing that.
Is this a bug in .odg import or is there some workaround that I am not finding?
