I solved this problem already by finding this thread previously :

https://support.mozilla.org/bm/questions/1399586

If your thunderbird window shrinks when being displayed on your internal laptop monitor but expands when displayed on an external monitor (or vice versa) it is because if the value for

layout.css.devPixelsPerPx (Edit -> Settings -> General -> (all the way down) Config Editor -> (search for) layout.css.devPixelsPerPx)

is set to a positive value. It seems like the value has a reverse effect in between internal and external monitors (shrink one and expands one).

To fix this issue, set the value for layout.css.devPixelsPerPx to -1

I am posting this question to display this solution to the public if anyone else experiences a similar issue.

You might also be interested to know that -1 is the default value of that setting.

Hi and thank you for your input. I marked the topic as solved with your answer so it will show up eventually.

You are correct that "-1" is the default value. I remember that i did change this value a while back for scaling purposes. Some answer i found online i can't remember where. I recall i wanted to scale up the UI on my external display, but doing so made Thunderbird very small on my internal display. It's funny because if i were to move the window with my mouse, the app is scaled up, unless any part of is dragged to display on my internal, then it scales down.

It's a weird behavior.

It was initially an apple behavior as far as I know. Something about pixel doubling on retina displays was where I first heard of scaling issues. As OSX is UNIX and Linux is really based on a Unix heritage, they probably share some of that.
