User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce:

Click attachement to open, or double-click it, or chose 'Open' from the drop down menu (save, open, detach, delete) at the bottom right.


Actual results:

A dialogue opens, and then shrinks immediately, to the small size, as shown in the attached image.  The dialogue is not resizable.

The behavior is the same for single attachement Open, as well as the Open All option.


Expected results:

I should at least be able to see my options under "what should Thunderbird do with..." and/or I should be able to resize the window so that I can see the dialogue properly

Product version: Thunderbird 52.9.1.

Does it happen also if, from the Help menu, you Restart with Addons Disabled?

I should have mentioned this earlier.  This happens with shift-click to start, and Help>Restart-with-addons-disabled.

Unfortunately, I can't remember the first release this started happening with.

Additional data point: this does not happen on a fresh installation of Thunderbird (tested on another macbook).

I've been using Thunderbird since 2004, letting it self-update; I probably copied the profile from windows to Linux to mac, and have gone through a few migration-assistant transfers with macbooks.

Is there an export, or backup-restore, that would allow me to do a fresh install and then restore my accounts and my inboxes/archives/folders?

antoun, do you still see this issue?

Comment 5

Yes, no change.  I am now running Mojave and TB 60.3.1

Anything I can do to collect diagnostic info?

cc some folks that might know what is going on

Do you use two monitors with different scaling like one Retina and one with normal scaling?

Comment 9

[antoun.kanawati]

I have two monitors (laptop and external), until recently, they were exactly the same scale (1920x1280).  With the new macbook pro, the laptop has a retina display.  Both are set for "default for display" (not scaled).

The issue predates the laptop upgrade.

The MBP display is automatically 200% scaled. On which monitor is TB and the attachment dialog? If different, try to open both on the same display and then please play a bit with opening on the displays.

Comment 11

[antoun.kanawati]

I tried the dialogue on the primary display, and it is now full sized. Reopening with TB on the second monitor works too, the dialogue pops up on the primary display.

I am now at 68.4.1.

Thanks for the tip.

Attachment: Debugging information as exported from version 132

Hi,

I simply wanted to jump in and explain my reproduction steps. I'm using Linux Debian 12, Thunderbird 128.4 as available in the distribution repositories. The problem, as far as I can tell, started happening with this version (128). Out of caution, I tested with the latest version available on the website and the bug is there as well, identical.



The comments on this bug helped me narrow down the problem: it does appear to be related to having multiple screens with different scalings.

I have two screens, one with high DPI and scaling, and another with regular DPI and no scaling. I noticed that the screen where Thunderbird starts will affect when the problem manifests, but not if it manifests eventually, if all reproduction steps are followed.

How to reproduce:
1. Open Thunderbird in troubleshooting mode, making sure that the screen where it opens is the "regular DPI" one
2. Try opening an "Open attachment dialog": it has the proper size, no truncation
3. Move the window to the "high DPI" screen
4. Try opening an "Open attachment dialog": it has the proper size, no truncation
5. Move the window back to the "regular DPI" screen: it is truncated
6. Move the window to the "high DPI" screen
7. Try opening an "Open attachment dialog": it has the proper size, no truncation

Alternative step to reproduce:
1. Open Thunderbird in troubleshooting mode, making sure that the screen where it opens is the "regular DPI" one
2. Try opening an "Open attachment dialog": it has the proper size, no truncation
3. Close the dialog
4. Try opening an "Open attachment dialog" again: it is truncated
5. Move the window to the "high DPI" screen
6. Try opening an "Open attachment dialog": it has the proper size, no truncation

I think Thunderbird might get confused with the conflicting DPIs and choose the wrong one. However, in certain cases, it works fine, probably unti lthe point it realizes there are more than one screen and then sticks to the wrong DPI.

I'll attach screenshots. I'm available for further debugging.

I might add that the window is resizable on my Linux environment (Wayland, Plasma 5.27.5), so it's not as severe, just an annoyance.
