Status: RESOLVED WORKSFORME

(Calendar :: Sunbird Only, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

I created a php service, which formats my school's schedules into ICS. Third
year students all have their schedule on only one schedule, so there are a lot
of events (up to five) which occur during the same period.

The ICS is well parsed but the calendar view shows some misalignments in random
places (It happens with two events or five, even when there's only one)

Reproducible: Always
Steps to Reproduce:
1. Use ICS attached in comment #2
2. Open Calendar (I use the firefox ext)
3. Go to week 46

Actual Results:  
Some of the events are overlapping by a pixel or two, the distance between
events varies, some lines disapear

Expected Results:  
Things should look flawless :)

Looks like rounding errors. Not a real big problem imo.

On one windows computer that I had forgotten Sunbird was installed on, the
display was fine. It ran a build of Sunbird from August 2004.

So my guess is something changed since then. I do agree the solution has to be
trivial but this "minor regression" looks awful.

I tried looking at the source code of the calendar XPI, but I didn't really know
how the files were linked, what function was called, where it was called and so
on. I gave up an hour later ...

After adding valid timezone information to the ICS file, you can open the calendar and there is no overlapping in the week view with the new calendar view code. But it's a good example for the badly needed "War on Boxes" (bug 304741).
