On the Calendar tab (with Thunderbird 3.0b1), with the Month or Multiweek display, the start times of events are slightly truncated on the left (so a leading "0" or "2" is not fully visible).

Works for me using Lightning 1.0pre (20090121) with Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1b3pre) Gecko/20090121 Shredder/3.0b2pre.

Attachment: Notice the 8's in 8:00 and 8:40 are being truncated on left

I have upgraded to:
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b3pre) Gecko/20090121 Lightning/1.0pre Shredder/3.0b2pre
specifically:
Lightning/1.0pre 2009-01-21-04 and Shredder/3.0b2pre 2009-01-21.

The problem still occurs -- see attached screenshot.

The versions of Thunderbird/Lightning I was running before used 24-hour format for events in the calendar -- these latest versions now use 12-hour AM/PM format -- is it posible to configure the calendar time format?

This is still a problem in 2009-01-25 version of Lightning and needs fixing for Thunderbird Beta 2.

I still can't reproduce this issue. While its quite unfortunate, I don't think this is major priority.

What type of calendar are you using? Does this happen with all calendar events?

Comment 6

[dave.r.wilson]

I'm not sure what your question "What type of Calendar are you using?" means -- I'm using the latest nightly version of Lightning.  This truncation occurs on all calendar events in both Multiweek and Month views.  It occurs in both 24-hour and 12-hour (AM/PM) clock formats.

This problem does NOT exist in Thunderbird 2.

I've tried using userChrome.css to see if I could fix the time truncation problem by increasing margins, padding,etc.  Whilst I could increase the margins, I couldn't get rid of the truncation.

However, when I was using DOM Inspector, I noticed that after clicking on an event with the DOM Inspector arrow cursor, the truncation disappeared and the time was displayed properly.  Does this give a clue to the problem?

I've also noticed that we are running different versions of Windows -- I'm running NT6.0 + en-GB -- you're running Windows NT5.1 + de -- could this make a difference?

With "What type of calendar" I mean if its a local calendar (i.e "Home"), or if it is a remote ics or caldav, or provider for google calendar, ...

I doubt Vista would make a difference here, but it would be nice if you could test on an XP system with your setup.

Comment 9

I am using a local calendar ("Home").

After further investigation, I think I can throw more light on the problem.  The truncation problem is not just confined to the event time -- it also happens in the event title with any title starting with a digit (but not letters!).  

I have tried changing the font-size and font-family of the event time, in three different ways using userChrome.css, as follows:

  calendar-month-day-box-item .calendar-month-day-box-item-label
  { 
    font-size: 10px !important;
  }  

  calendar-month-day-box-item .calendar-month-day-box-item-label
  { 
    font-family: Arial !important;
  }  

  calendar-month-day-box-item .calendar-month-day-box-item-label
  { 
     font-family: Microsoft San Serif !important;
  }

All of these avoid the truncation problem, but of course the displayed time is in a different style to the rest of the calendar text.

I suspect the problem is to do with the particular font used in Lightning, and perhaps the formatting of the event time/title text (trying to squeeze in as much as possible into a small space).

Maybe a Vista-problem. I can confirm this report using 
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1b3pre) Gecko/20090202 Lightning/1.0pre Shredder/3.0b2pre

Probably related: I see the same bug in the popups of the download status bar extension/firefox 3.0.5.

Comment 12

[dave.r.wilson]

I have confirmed that this problem exists in both Vista 32-bit and Vista 64-bit.

This problem has been introduced in Lightning/1.0pre -- it was NOT present in Lightning/0.9 with Thunderbird 2 on Vista.

Comment 13

[dave.r.wilson]

The problem reported in Bug 476620 (marked as a duplicate of this bug) also exists in both Vista 32-bit and Vista 64-bit.

Adjusting summary to include bug 476620 (marked as duplicate of this one).

Comment 17

[kong.ben]

Wanted to add that this problem exist for me using:

Win 7 Pro x64
Thunderbird 3.0.1

Comment 19

[mbradleynews]

This also happens for me using Win 7 Pro x64 and Thunderbird 3.0.1

I hacked a fix for my machine by changing the calendar-views.css file inside calendar.jar (for me that is located under C:\Documents and Settings\{USER}\Application Data\Thunderbird\Profiles\{random_chars}.default\extensions\{some_key_string}\chrome\).  I added a line under calendar-month-day-box-item so that it now looks like this:

calendar-month-day-box-item {
    margin: 1px;
    padding: 0px 1px;
	font-family: Arial !important;
}

but as is mentioned above, that changes the font for all of the events

This problem can be fixed by using the 'Calendar Tweaks' Add-on :

Attachment: TB 3.03 compared with TB 3.2a1pre

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.3a3pre) Gecko/20100308 Lightning/1.1a1pre Shredder/3.2a1pre

On my Win XP with system font Segoe UI this issue is partially present (only 1 pixel), but with the latest Thunderbird's nightly I've noticed that the issue has disappeared (see screenshot).
Could someone with Windows Vista or Windows 7 verify whether something has changed with Thunderbird's nightly (Shredder) 3.2a1pre later than 2010/03/07?

Lets assume this is fixed somewhere in the platform. If someone has this issue with 1.0b4 or later, please reopen.
