Suddenly after years, I can only print text

I have latest release of Libreoffice and for years I have been creating maps by pasting a screen cap and adding text and then printing out Page. All has worked fine. then overnight,only the text will print. The print preview shows what I want. I can export to PDF and then the PDF will print text and picture with Foxit PDF viewer but if I open the PDF in Libreoffice it will only print the text. In the printer setup options menu the pictures and objects box is ticked. Tried resetting profile, no help.What gives

You are almost certainly hitting the OpenGL/OpenCL bugs which affect images, but not text (although there is also a report of italic text being affected!). See response to Q64314. Fixed December 2015.
