I do have the same Issue with the latest version of InDesign.
It works fine for a couple minutes and after copy&pasting text from other documents or typing in new text, all the text disappears.
Minimizing and maximizing the InDesign window makes the text visible again until I try to type again.
If I restart InDesign or the wohle computer works fine again for a while.
The more I copy from other InDesign chapters, the quicker it disappears.
Hopefully there is help outside...
sorry for the late reply.
Nothing really helps so far. I tried out the restoring but it´s still the same problem.
No matter, which document I open for work. Whenever I copy too much stuff from another chapter (always with tables) the text disappears.
The only solution (which acutally is no solution) is restarting Indesign or rebooting the computer.
All updates from CC are done.
It´s a nightmare
