Status: RESOLVED DUPLICATE of bug 1179283

(Core :: Widget: Win32, defect)

Description

Attachment: firefoxbug.png

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150630154324

Steps to reproduce:

Using a 4k screen, on windows 10 with the display scaling factor set to the recommended 225% for a 15" screen, open enough tabs such that the right side of the last tab is near the minimize button.


Actual results:

The minimize button overlaps the "new tab" button, such that it is nearly impossible to click (there seems to be a small gap of a few pixels at the bottom).


Expected results:

The tab width should have scaled properly so that UI elements don't overlap.

Is it the same behavior with FF39 on Win 7/8?

Comment 2

[:Gijs (he/him)]

This issue is fixed in Firefox 40 and later.
