Details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:107.0) Gecko/20100101 Firefox/107.0

Steps to reproduce:

I started Firefox Nightly 107.0a1 (2022-10-14) on Wayland with WebRender compositing in Plasma 5.25.5 in a Fedora 37 KDE Plasma installation. I had previously enabled the menu bar. I clicked on Bookmarks in the menu bar. I moved the cursor over a bookmarks folder with about 30 bookmarks.

Actual results:

The contents of the bookmarks folder sometimes flickered. The bookmarks folder didn't show the down arrow like a V at its bottom which allowed scrolling down as was present in previous 107.0a1 builds. Firefox's interface sometimes became unresponsive for a while after the flickering problem occurred.

This problem didn't happen with 107.0a1 (2022-10-13) on Wayland and earlier. I ran mozregression --good 2022-10-13 --bad 2022-10-14 -p ~/.mozilla/firefox/z8d4nvrc.default-nightly --profile-persistence reuse

Bookmarks folders with fewer bookmarks which don't usually show the down arrow don't show this problem.

Expected results:

The bookmarks folder's contents would be shown normally with the down arrow allowing scrolling down through the bookmarks. Firefox would remain responsive.
