1874572 - [Wayland/KDE]Firefox on wayland does not handle file drop events correctly

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect, P3)

Description

[quantumphoton007]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

Open https://copilot.microsoft.com
Alt-tab to a different window
Alt-tab to firefox

This issue is not specific to copilot.microsoft.com. I can reproduce the same on slack. Neither of these are problems on chromium.

Actual results:

Instead of the text input at the bottom, there's a persistent "Drop image here" area

Expected results:

The text input must have stayed as-is. I did not drag anything over firefox, so firefox should not propagate any drag-drop events.

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.

Can you create screencast of the issue?

Also can you check X11 backend if it's Wayland specific?

Thanks.

I updated to firefox 122 a while ago and I can no longer reproduce this on copilot or slack. I have never seen this before on X11. I remember seeing this since october last year, which is approximately when I switched to wayland. Let's mark it as "can't reproduce" and I'll reopen the issue with a screencast once I can. Thank you for the follow-up.

It's interesting, Thanks. Can you try to run Firefox under X11 to check it's Wayland only?

Thanks.

Hey Martin, I'm sorry for missing your reply. I can no longer reproduce it on wayland. Also I have not seen this bug appear in the past couple of months so I think we can consider this resolved.
