OK I did a test which seems to throw up the inconsistent font issue is a totally reproducible way - and the test is very simple indeed. I am using version 18a2 linux 64 bit version from 4th November but this test can be applied to any version that other testers following this bug can also try.
The test is as follows: 1) Click "Write" to begin composing a new mail. My default font is set as medium, and sans-serif. 2) Now type direct into the main text box "This is a test " - 3) Now highlight the text you have just entered with the mouse and right click and copy. 4) With the cursor set at just after the last space in the text entered now right click and select "Paste without Formatting" The result is that the two phrases which should be identical are now of different font size. I will attach a screenshot in a sec showing the two different fonts in this text as highlighted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/584632 Title: composer changes font mid email To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/584632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
