Status: NEW

(Core :: Widget: Gtk, defect, P5)

Description

[BB_C]

Attachment: ff.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0

Steps to reproduce:

No GTK3 theme is set, `~/.config/gtk-3.0` is empty.
No DE installed.
DPI is set via `Xft.dpi` in `~/.Xdefaults`.

Checkbox scaling seems to be broken (screenshot attached). The box itself is scaled, but the check symbol is not.

Leaving as Untriaged as this could be a layout issue, or a GTK issue, or both.

Please ignore the User Agent included. This has nothing to do with Firefox/52.0. The issue exists with the latest stable, beta, and nightly (webrender on and off).

Using HIDPI (set layout.css.PixelsPerPx = 2) the checkbox is not scaled, the checkbox label is scaled. Tested on Ubuntu 18.04 x 64, using Firefox 90.0b6. See this issue in the attached screenshot: Screenshot from 2021-06-11 10-16-33.png

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
