2036996 - Dark mode rendering not removing light external background on Windows 11 in certain circumstances

Status: RESOLVED FIXED

(Thunderbird :: Message Reader UI, defect)

Description

[Max Emig]

I can't share a sample yet, it is an incredibly complex e-mail with personal information with external content enabled I failed to sanely redact.

On Linux and macOS it renders correctly, on Windows 11 it blinks correctly for ~0.5s before falling into this incredibly broken white text on almost white background.

The following conditions apply here, some may not be decisive:

• .root-container { background-image: url(lavender.png) !important }
• background:#FFFFFF;background-color:#FFFFFF
• bgcolor attribute on 8 outer <table> elements
