User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0 Build ID: 20150630154324 Steps to reproduce: Apply Any Theme (other then default) Actual results: When I apply (or preview) any theme (even a recent released one) Min/Max/Close buttons partially hidden behind the theme. The buttons are totally hidden by the theme in safe mode. The buttons show fine with the default theme. Expected results: Should be able to see the full buttons when a theme is used.

It's probably a dupe of bug 1089312 with Aero and theme. Could you type about:support and paste the section "graphics", please. The workaround is to use a different theme.

I've tried many themes all of them have the same problem.

I tried disabling OMTC that didn't fix the problem. All my drivers are up to date.

I was testing earlier the only way to get the buttons to show fully with a theme applied is to show title bar. I like Firefox better without the title bar so I hope the issue can be fixed in the future.

I don't have Windows 10 yet to confirm. Are we supporting Windows 10 in Firefox 39?

Dawn, can you please provide me steps to reproduce from a default clean state? I've tried loading several themes and have not been able to reproduce this. (In reply to David Anderson [:dvander] from comment #5) > I don't have Windows 10 yet to confirm. Are we supporting Windows 10 in > Firefox 39? David, I believe the first version we plan to support in Windows 10 is Firefox 40. That is the first version with any Windows 10 specific changes (eg. theme integration).

I stumbled upon several rendering oddities while testing with the High Contrast #1 theme that ships with Windows 10. This screenshot shows comparisons between Firefox in various states. From top to bottom: 1. Nightly default Firefox theme and High Contrast #1 Windows theme 2. Nightly in Customization mode with the High Contrast #1 Windows theme applied 3. Thunderbird 38 with the default Thunderbird theme and High Contrast #1 Windows theme applied. (Firefox should probably look like this). 4. Thunderbird 38 after switching from High Contrast #1 to default Windows theme (notice rendering issue in tab strip and content) 5. Nightly 42 after switching from High Contrast #1 to default Windows theme (notice similar rendering issue to Thunderbird) 6. Nightly 42 with the titlebar enabled using the High Contrast #1 Windows theme 7. Windows Personalization window with the High Contrast #1 theme (illustrates how a Windows application is designed to work with the theme - probably a good baseline). Note the issues I've called out above seem to "fix" themselves if I restart the application. I'm not 100% sure that all of these are illustrative of this bug but I've added them here for reference. Dawn, this comment does not invalidate my previous request for steps to reproduce. I still need this information so I can precisely replicate what you are doing and therefore know that I'm seeing the same issue.

I'm not sure what you want as far as steps, but here is what I just did. (I'm running the default Windows 10 theme in windows) 1. I refreshed Firefox 39 to remove all add-ons & settings 2. Added a new theme: https://addons.mozilla.org/en-US/firefox/addon/mareilhas/ The buttons are still hidden unless I show the title bar or use the default theme.

I think I'm getting confused with the ambiguity between Firefox themes and Windows themes. What Windows theme do you have applied? Also, the URL you provided in step 2 is 404.

The Windows Theme I have is under Windows Default Themes: Windows 10 (it comes with 10 I did not download it). Firefox theme: https://addons.mozilla.org/en-US/firefox/addon/tranquil-blue/ (altho I tried over 20 themes & they all block the buttons the same way)

I am unable to reproduce this with the default Windows 10 theme and the tranquil-blue Firefox theme. I tested with the latest Firefox Nightly though. Can you try the latest Nightly from https://nightly.mozilla.org/ and see if this still reproduces? You should also check the latest Beta from https://beta.mozilla.org/ since that's the first version we plan to support with Windows 10.

I installed the Nightly & the beta, the buttons work fine in both (without showing the title bar). Glad to see that 40.0 will fix the issue.

Thanks for checking, Dawn. You won't have to wait too long as I think Firefox 40 is a couple weeks away from release (August 11 if it remains on schedule). [Tracking Requested - why for this release]: nominating to track for awareness just in case this shows up in feedback reports. However I think this bug is WONTFIX.
