1477933 - Firefox title bar appears even when disabled, and changes minimise and exit icons to look like windows 7

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[GammaRay]

Attachment: Firefox Windows 7 title bar bug.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0
Build ID: 20180704003137

Steps to reproduce:

It happens if I load any web page, but it only happens sometimes. It reverts back to normal in half a second or if you click out of the window, which makes it really hard to reproduce or take screenshots of. Luckily, I was able to get a screenshot eventually.


Actual results:

The Firefox title bar appears, even though it is disabled in Customize. It then makes the Minimize, Full Screen and Exit buttons look like they are from Windows 7. I use a Windows 10 laptop.


Expected results:

The title bar should not have appeared and the Minimise, Full Screen and Exit buttons should not look like Windows 7 buttons.

Hi, 
Thanks for taking time to report the problem, I tried to reproduce this issue using Firefox 61.0.1 (64-bit) (2018-07-04) as well as on Firefox Nightly 63.0a1 (2018-07-26) but without any success.

Can you share a few more steps in order to reproduce this problem? (web pages visited, number of tabs opened) 
Can you reproduce this issue in other browsers as well?
Are there any Extension, Add-ons or Themes installed that may cause this issue?
Can you try to reproduce this issue on the latest version of Nightly you can find here: https://nightly.mozilla.org/
Also if the issue persist can you also try to disable hardware acceleration from Options menu: about:preferences -> Performance -> uncheck "Use Recomended Performance settings" - uncheck "Use hardware acceleration when available"
Are your Graphic drivers up to date ? Graphic Cards might also cause a switch from Aero to Basic from time to time.

This issue is not reproduced in any other browsers on my computer, only Firefox. I have tried Chrome, Edge and even Internet Explorer, and none of them have this problem.
Six tabs were open: My blog on Edublogs, Code.org, YoYo Games, Bugzilla, Google and a new tab.
I have no add-ons or themes and my only extension is Adblock.
My graphics driver is NVIDIA GEFORCE GTX version 3.14.1 which is the latest version.

I still need to try to disable hardware acceleration and try reproducing the bug on Nightly but I don't have the time at the moment, tell me if you need more information.
