Status: RESOLVED INCOMPLETE

(Thunderbird :: Untriaged, defect)

Description

[Mark Kennedy]

Attachment: Thunderbird changing size and apparent resolution while freezing temporarily under Windows 10.png

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:40.0) Gecko/20100101 Firefox/40.0
Build ID: 20150826023504

Steps to reproduce:

While migrating through different folder, e.g. from in to Sent box have random 'freezes' and changes in Thunderbird apparent screen/resolution size.

This began after I updated to Win 10.


Actual results:

For about 10 seconds Thunderbird stops responding while the screen has reduced in size from full screen to partial and the apparent resolution has changed.

I took a screen print with Thunderbird 'not responding'.  Note that it was in full screen mode and has reduced in size and moved to the upper right of the screen.


Expected results:

Folder should have opened without the window or resolution size changing.

Start *Windows'* safe mode with networking enabled
