Status: RESOLVED DUPLICATE of bug 909820

(Thunderbird :: Theme, defect)

Description

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140716183446

Steps to reproduce:

Hovering the mouse over the folders in the Folder Pane, several white lines appear leaving a trail where the mouse was moved.

This error happens only with version 31.0-candidate (ftp://ftp.mozilla.org/pub/thunderbird/nightly/31.0-candidates/build1/win32/en-US/Thunderbird%20Setup%2031.0.exe).

Version 24.7.0-candidates works correctly (ftp://ftp.mozilla.org/pub/thunderbird/nightly/24.7.0-candidates/build2/win32/en-US/Thunderbird%20Setup%2024.7.0.exe).

To test I installed thunderbird (31.0-candidate) on 4 different computers and the error always happens the same way.

All computers used for testing have Ultimante Windows 7 (64-bit).

One is configured with a video card from NVidia
Another uses a video card from ATI
And the last two use the Intel video card
