1115990 - Add an option to Prefs/Advanced to enable/disable the hardware acceleration

Status: RESOLVED FIXED

(Thunderbird :: Preferences, defect)

Description

[Richard Marti (:Paenglab)]

I had multiple times in bugs to ask users to disable the HWA to test if this would fix the issue. Now we have to guide the users to use the about:config editor and change 'layers.acceleration.disabled' and additionally on Windows 'gfx.direct2d.disabled'.

It would be easier to guide the users with "uncheck the hardware acceleration on Prefs/Advanced/General".

Firefox/Seamonkey have this option already at this position.

Hmm, if it really does something only for windows, why it is shown (and enabled) for other OSs?

On all platforms it changes 'layers.acceleration.disabled' directly in XUL <preference> and on Windows additionally 'gfx.direct2d.disabled' through JS.
