Status: NEW

(Firefox :: Site Permissions, defect, P3)

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/61.0.3163.79 Chrome/61.0.3163.79 Safari/537.36

Steps to reproduce:

- Initiate a 1:1 call with Cisco Spark (any similar website using screen sharing should do)
- Attempt to share the screen with the other person


Actual results:

The UI of the screen sharing dialog is broken, I can't click the "Allow" button because the screen sharing preview overlaps the approval buttons, as you can see in the attached screenshot.


Expected results:

The UI would allow me to click the Allow button.

Hm, I can't reproduce this on Ubuntu or any other OS for that matter. Is this on version 56? Can you try the latest Nightly and see if the issue persists?

It was 56, and I also saw it with the 57.0b7, where it also looks strange, but at least I can click on the Allow button.

I guess it may be caused by my multi-screen setup: I have a laptop with 1920x1080 resolution and two external monitors with 2560x1440 each.

I'll try to also reproduce it with less of my screens enabled in the display settings.

Is this with a non-default window manager that somehow affects sizing of the permission panel?

No, I am using unity.

I confirm that the issue is not reproducing with a single screen. I will check with two screens tomorrow.

Hi,

I have managed to reproduce the issue on Ubuntu 18.04, in latest Nightly 68.0a1 (2019-05-06), latest Release version 66.0.3 and latest Beta version. It is the same behavior like in the photo from comment 3.

Reproducible in the Latest Nightly 69.0a1 (2019-07-01).

Is this still an issue? On Fedora 34 GNOME Wayland this works fine.
