Hello! I have tried to reproduce the issue using firefox 89.0b15, 88.0.1 and 90.0a1 (2021-05-24) on Ubuntu 20 but unfortunately I wasn't able to reproduce it.
Could you answer the following questions in order to further investigate it and be able to reproduce it on our end.

1. On what resolution did you encounter this issue?
2. Could you please attach the about:support info?

Thanks for looking into this; the resolution I used was 3840x2400 and the support info is attached.

Just to note, I found this issue when using UI scaling in gnome 3.38 using wayland. Now that I've switch back to X, the previews look normal.

Hello muhmud! Thank you for the reply! Unfortunately I wasn't able to reproduce the issue on Ubuntu 20 with the resolution you mentioned in comment 3. Here is a link with a more detailed view of the system specs used: https://imgur.com/a/qmQwtm2 .
Is there something else I could've done, if so please let me know

Thank you!

Reporter not responsive for a year now and the issue might have been fixed, closing.
