Firefox tooltips not constrained to screen if another popup is open

[zootedb0t]

Steps to reproduce:
Hover over an interactive element, such as the close tab button or hamburger menu.

Actual results:
• Sometimes tooltips are only partially visible—part of the tooltip appears off-screen.
• When tooltips do appear fully on-screen, their positioning is still incorrect.
• The same positioning issues occur with hamburger menu items (such as the “History” menu).

Expected results:
Tooltips should stay fully on-screen and appear close to the cursor when hovering over elements like the close-tab button or hamburger menu.

I have opened a bug report on Firefox bugzilla as well. But they said that this doesn't happen on other wayland compositor.

Can confirm, i have had this happen for atleast since .46 so its no recent regression i think

It happens for me too in Firefox. There is definitely something wrong with rendering in Hyprland, as the tooltip is not cleaned up properly afterwards, see video for what I mean:

I do not have this specific issue where the tooltip goes off-screen, but I'm more concerned about the weird rounding of the tooltip corners.
