The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Also would be great to test latest nightly directly:

Thanks.

Reproducible by changing intl.l10n.pseudo = bidi on latest Nightly 131.0a1 (2024-08-11) Ubuntu 24.04 Wayland.

Most toolbar menus flicker rapidly when the mouse cursor moves over them, except for the File, View and Help menus. It does not happen with XWayland.

Looks like a regression from Bug 1823552. When https://phabricator.services.mozilla.com/D173135 is reverted the menu doesn't flicker (but it's slightly moved).

Emilio, any idea here?
Thanks.

We flip the position / anchor alignment on rtl, so we have to choose
different resets there to end up at the requested position.

:emilio, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.

This needs bug 1901769 to graft cleanly, which was previously not approved for uplift to Beta. That said, we probably want to take this on ESR128 next cycle alongside that.

[Ina Popescu, Desktop QA]

I've replicated this issue using Nightly 131.0a1(08-08-2024) RTL on Ubuntu 22.04 Wayland following the STR from Comment 4.
Verified as fixed in the latest Nightly 131.0a1 RTL on Ubuntu 22.04 Wayland, as the issue no longer occurs.
