1185829 - After upgrading to 38.1.0 UI is rendered vertically offset and unusable in Windows 7

Status: RESOLVED INCOMPLETE

(Thunderbird :: Mail Window Front End, defect)

Description

[rossb]

Attachment: Main Window, showing display vertically offset.

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.81 Safari/537.36

Steps to reproduce:

I upgraded to Thunderbird 38.1.0
On Windows 7 SP1 Professional
I launched Thunderbird


Actual results:

In the main window, the display is rendered vertically lower (see screenshot)

In other windows (About window, compose, alert) the display is rendered vertically higher and the top part of the window is not visible.

In all cases, the mouse seems to respond to where the display should be rendered.

It is very difficult to operate the UI when you can't easily click on things.

I have tried this with gfx.direct2d.disabled both set to true and false.


Expected results:

Display should be rendered at correct location.

Does it happen in safe mode? https://support.mozilla.org/kb/safe-mode
Do you have the newest version of graphics driver?

No.

Yes. FYI: Intel HD 3000 on a 3+ year old laptop

Did you figure out which add-on was causing it?

I didn't think to try. Does safe mode only disable add-ons?

Comment 8

[Magnus Melin [:mkmelin]]

Mostly yes. (Also some other minor things like using the default toobar items and such.)

I have disabled all add-ons and the problem persists.

No plugins are enabled either.

Disabling hardware acceleration seemed to fix it.

As far as I know it's the default theme.

The previous dump was with hardware acceleration disabled in the advanced options. Now here is the dump with acceleration enabled and the bug present:

I'm reopening this because the but is still present when hardware acceleration is enabled, with no plug-ins enabled.

rossb, 
Do you still see this when using beta from http://www.mozilla.org/en-US/thunderbird/channel/ or version 45?

Note - similar issue reported in bug 1185205

The bug is still present in 45.5.1 (release channel)

Specifically: when "Use hardware acceleration when available" is selected in Options > Advanced > General, then the UI is offset as in the screenshots attached to this ticket.

Sorry, I'm running a business here. I'm not prepared to run a beta version.
