Strange characters and symbols when opening a PDF document.

Hello. For about 1 month, when opening certain PDF documents that we generate from our ERP, using a PDF printer driver, on some computers with Adobe Reader in its latest version, strange symbols and characters are displayed in certain parts of the document.
More specifically in the parts of the document that have Arial Bold as their font.
At the moment we solve it by restarting the computer and when you open the same document again, as soon as you open it it continues to be displayed badly, but in an interval of 2 or 3 seconds it is automatically corrected and it can now be viewed correctly.

This happens again at random after 1 or several days.

Could you confirm that it may be happening? Because until 1 month ago this did not happen.


I attach two images with examples of both cases


Thanks a lot
