I have been using Lightroom for several years and have not run into this problem until now. I used to and usually would run Lightroom Classic on my computers which were Windows machines. I really enjoyed using the book module as I liked for each year creating a book of the best photos I took during that year and then I could easily export it to a PDF and have it printed.
However, I recently purchased a MacBook Pro which runs Lightroom incredibly well. But there is a problem in the book module now which was not there on my Windows computers or even this computer a few days ago. The text which I am typing comes up looking incredibly pixelated. When I export the PDF the text looks razor sharp (how it used to look when in the book module), but while typing or looking at pages which already have type on them there are pixelated blocks around the text, I will attach a screenshot to show what I mean. I already checked that Lightroom is not opening in Low-Resolution mode and that did not fix it. The rest of the text in Lightroom looks fine (the system text or the develop settings for example) it is just the text actually in the book.
I hope someone may have found this issue before and knows a solution thank you!
