TB 102.6.0 (32-bit) Dark Mode calendar updates not readable

I use Dark Mode. For the last couple of updates, the calendar email notification text doesn't display the same way a regular email does. The calendar itself is fine. Received email is fine. Composing email is fine. Although, the a bright white background in received/composed email works, it is harsh, especially at night. I can't read the calendar reminders that are sent by TB.

I just noticed today when I was going to make this report that I'm using a 32-bit version. Is there a 64-bit version that I should be using?

I understand it is a massive undertaking to convert and maintain the code and appreciate the time and effort it takes to support the product.

I've just deliberately gone onto gmail and sent event attendee to one of my email addresses to get a notification from google calendar. I'm testing in 'Troubleshoot Mode' (Safe Mode) because I've got userChrome.css effecting sections of display.

Although my email is an invite and the first part x has invited you etc is using a much paler text so is readible. The remainder about the 'Metting Link' etc - the general style looked like the same dark background and grey text and not so easy to read.

Why?

First you need to understand that the email is not sent by Thunderbird. It is sent by gmail.

Gmail in their wisdom are sending these notifications specifically using those colours. Gmail have composed their notifications using a microsoft product, which seriously bloats the email code and not all of microsoft coding is useful in non microsoft products. But the bottom line is this - gmail is controlling the html coding in the email. Gmail has chosen to display grey text on dark grey background if use is using a 'dark theme'

If you open email to view in Message Pane, then click on 'More' and select 'View source' you can see all the code. Thunderbird can only display what the email content dictates if you are viewing in 'Original HTML' mode. Gmail have messed up and created the problem.

If you use 'View' > 'Message Body as' and select 'Plain text' then it is much easier to read as all the formatting is stripped. I suggest the above option as it is easy to quickly switch back after reading email.

Otherwise, the alternative is to do a temp switch in theme to 'Light' OR a temp change in 'Settings' > 'General' In the 'Language & Appearance' section click on 'Colours' button Make sure 'Text' is 'black', 'Background' is 'white'. Do NOT select 'Use system colours' for 'Override the colours etc.....' Normally, I would advise you select 'Never', but selecting 'Always' and click on 'OK' will force the display to use those settings. But this setting may not be generally desirable.

Selecting Plain Text seems to work the best. I understand the issue, though. Thank you for your help.
