Status: RESOLVED WORKSFORME

(Calendar :: Calendar Frontend, defect)

Attachment: Calander issue.png

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0

Steps to reproduce:

The problem began with the latest update to version 60.0.

Open the Lightning Calander.


Actual results:

Look at the top left hand pane in my screen shot. Note that the colours are now reversed compared to the rest of the interface. Also note that the year and month cannot be seen so it's become very difficult to change dates to another part of the year or other years.


Expected results:

The colours of the left hand pane should be the same as the rest of the interface, and were prior to the v60.0 update. Many years ago I applied a high contrast accessibilty theme. So many years ago I can't recall what I did. But that theme now seems to be broken.

The theme may simply have allowed the Microsoft Windows theme colours to be used. Or may have set foreground/background to white text on a black background. (My windows thems sets white text of a black background)

It could be related to the setting, or  not setting, of all foreground and background colours. Setting some but not othere results in unpredictable outcomes such as this.

I see this too with TB 60.
Set the pref calendar.view.useSystemColors to true and check the minimonth on the left. It has still the yellowish today button. When I start the devTools  it changes to the systemcolors.

Geoff, could this be a problem with the overlay loader? With Daily I don't see this issue.

No, it can't be the overlay loader, since the reporter has version 60.

It's happening because where we set the colours for the mini-month, we don't also set the colours for the toolbar buttons in the mini-month. It also happens where the mini-month is inside a menulist, e.g. the event dialog date picker.

I just wanted to confrim that the problem is still present in TB 60.8.0 (32 Bit) with Lightning 6.2.8.

Thanks everyone.

PS.

Prior to TB 60.0 the mini-month pane appeared the same as the rest of the window ie. white forground on black background.

Some years ago I was advised (an old bugzilla report) to turn on Accessibility within TB/Lightning. It was so long ago I can't remeber exactly and wouldn't know where to look in the latest UI to turn on "high contrast" colours. It had been working very nicely for a long time.

This problem seems to be fixed in TB 68. Thanks to all who worked on it.

But I'm afraid a similar problem has now appeared when open ing the drop-dwon lists to enter the start time or end time of a Event. The background colour of the Minutes pane is wrong (hours are OK). I'll open a new bug report for this.
