I edit books and as I go along I will notice that some of the text is missing. This occurs randomly. When I select the text with my mouse I see what is pictured in the attached screenshot.
To correct it I simply change the size of the font and it will go back to the correct text and format.
I have tried reinstalling Indesign several times hoping that it would solve my problem. I also called Adobe support more than once and did not get a solution.
I am working on a dell pc and running Adobe Indesign 2021.
Can you confirm that your memory and video card specifications match the recommended values for InDesign.
Also, do you have other programs running at the same time?
Is it a new issue since you upgraded/updated something?
Have you applied by accident a Character style that might interferre?
Try unticking GPU Performance under the GPU Performance tab in InDesign preferences then closing and reopening the application.
I could not find the option of unticking GPU Performance. Did a search to see where it is suppose to be located within Indesign but it wasn't there.
I have stopped running any other program that Acrobat and so far so good.
