Technical issues with version 21 repeat in version 20
I apologize if this has been discussed recently, but I was unable to find any relevant threads.
My new Adobe 2026 (version 21.0.2) exhibits a number of issues which make work very cumbersome:
- Entire paragraphs blank out (especially when I’m marking text for editing), and only reappear after scrolling the blank space out and back into the editor window, or clicking somewhere else on the page.
- The editor is very sluggish, regardless of GPU performance settings.
- Some paragraphs are not aligned on screen correctly (letters stick outside frame, etc.) - however, they become properly justified in exported PDF documents. Switching between Adobe Paragraph Composer and Adobe World-Ready Paragraph Composer usually fixes this issue for a given paragraph, though.
- The Undo history gets lost.
I have reverted to the previous version (20.5.1) but now somehow exactly the same issues started appearing in this one as well. I have already tried the typical fixes (clearing the program cache, resetting the preferences), but nothing helped so far.
It’s not a singular problem limited to a single system - my two machines, a desktop and a laptop, behave in exactly the same way (both running Windows 11). Any suggestions for possible solutions?
Thank you!
Adam
