Created attachment 1633838 [details] Image of firefox-wayland at 200% scale (no scrollbars shown) Description of problem: Firefox UI Scrollbars (bookmarks, history) do not render under Wayland when using a 200% scale factor (highdpi). Version-Release number of selected component (if applicable): [matt@localhost firefox]$ firefox --version Mozilla Firefox 70.0 How reproducible: Easily, reproduced on baremetal and in VM. Steps to Reproduce: 1. Create enough bookmarks (or history) items to require UI scrollbars. 2. Set Scale factor to 200% (In Gnome Settings / High DPI display) 3. Click the library button in the toolbar, Bookmarks. No scrollbars present (they only work at 100% scale (Wayland) or in Firefox-xorg) Actual results: Scrollbars not present for UI elements. Expected results: Ability to scroll through bookmarks (and history). Additional info: Images of behavior attached. Will follow up with example bookmarks export.

Jan, can you look at it please? Thanks.
Matt, can you try to reproduce it with latest firefox nightly binary? How-to is here: https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries Thanks.
Martin & Jan, Thanks so much for the quick follow-up and for maintaining Firefox on Linux. I tried Firefox Nightly on Rawhide, behavior here is different but still not quite correct. Very Interesting... In this case scroll-bars do appear; however, the menu doesn't properly scale within the firefox window / screen size. As a result, the menu runs off the bottom of the screen and it's impossible to reach the lowermost items (cannot reach the "Show All Bookmarks Ctrl+Shift+O" UI decoration). I'll update the bug title to be more in line with this finding. Screenshots to follow this comment. Thanks again -MK

This also impacts other items that require scrolling such as the tab listing when you have a large amount of tabs open.
This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle. Changing version to 32.
This message is a reminder that Fedora 32 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '32'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 32 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
