1827832 - Misplaced tooltip on Developer Tools

Status: RESOLVED INCOMPLETE

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

Description

Attachment: dev-tools-hover1.png

Details

The tooltip displays too far off.

STR

• Open https://developer.mozilla.org/en-US/docs/Web/API/History_API
• Open Developer Tools F12 (tested with Dock to Bottom & Separate Window)
• Select an h2 in the Inspector
  e.g. <h2 id="concepts_and_usage"><a href="#concepts_and_usage">Concepts and usage</a></h2>
• Hover over var(--type-heading-h2);
• Also hover over var(--heading-letter-spacing);

There was another placement issue which was limited to Wayland. If you cant reproduce it, that might be the reason.

Tested on: Ubuntu 22.10 Wayland, Nightly 114.0a1 (2023-04-12) (64-bit)

As mentioned, tested on Nightly 114.0a1 (2023-04-12) (64-bit)
Build ID 20230412092401
However, the bug was initially posted to #devtools:mozilla.org on Fri, Apr 7 2023.

Which part of about:support is needed?

Can you use mozregression tool to find broken commit? You need to run it with MOZ_ENABLE_WAYLAND=1 env variable.

Thanks.

mozregression GUI doesn't run on my set-up and I am not familiar with the CLI version.

Previously: Bug 1749215

You just need to open terminal and run:

pip install mozregression
MOZ_ENABLE_WAYLAND=1 mozregression --good 100

mozregression will open new Firefox window, you do the test here ans switch back to terminal and type g/b according the test result. That's all.
