1584487 - Themes do not work properly on Windows 7

Status: RESOLVED FIXED

(Thunderbird :: Theme, defect)

Description

[Janos Kövari]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

After upgrading to 68.1, only the default theme works. The light or dark themes don't: there are no window borders, titlebars, minimize/maximize/close buttons, nothing, when opening messages or anything in a new window (I'm not using tabs).

Actual results:

No window borders visible, can't close windows. (If using the setting to open new windows for everything instead of using tabs.)

Expected results:

Windows should have their usual borders and stuff.

Those themes work. Please try with add-ons disabled, see Help menu.

The Default, Light and Dark themes all work for me using Thunderbird 68.1.1 on both Windows and Linux. With and without "Show Title Bar" enabled in the Customize window. My preference is to show the title bar.

Could you try using safe mode? Use Help > Restart with Add-ons Disabled.

Started my old PC with Win7 Aero...and yes, only on Aero the window has no window frame. restricting the rule to only the main window fixes it.

I couldn't have helped anyway, got so pissed I switched back to 60.9. this new version is just useless, soooo many bugs. :(

Sorry, I can't test this. My Win 7 box is 1800km away and hasn't been started in years. But I understand people hanging on to it since Win 10 made a bunch of hardware obsolete :-(
