The list view is displayed with a small border radius. This looks nice most of the time, but not always. The attached screenshot shows the problem. This is most likely a Linux platform bug.

It's visible on all platforms. I wonder if this is a core issue.

Filed a separate layout bug (bug 597927). If that can't be fixed for 4.0, we can add a margin to the richlistboxes (and the browser element in the discover view).

One or the other must be fixed for final (though adding margin would suck a lot)

You should just be able to use 'overflow:hidden'. If you can't, please reopen bug 597927.

Setting overflow: hidden only works if the container can be scrollable which decks aren't, however we can wrap the deck in a box which is to fix this.

Note this also takes the chance to correct the indentation of the categories list.

Scrolling up on the Get Add-ons pane seems to cause this weird painting issue. It fixes itself after a 3-4 seconds though. Is this a known issue?

Comment on attachment 477602 [details] [diff] [review] patch rev 1 r=me, dependent on how bad the issue in comment 9 is deemed to be. It doesn't seem huge to me, since its only the Get Add-ons pane when scrolling up, and disappears in a few seconds. It could probably be hacked around here (with margins - see comment 4), but it looks like something that should really be fixed in the platform.

That issue is actually pretty bad. We need a layout bug filed on it at least.

(In reply to comment #11) > That issue is actually pretty bad. We need a layout bug filed on it at least. Reopening bug 597927?

No, a new bug. Bug 597927 was about stuff not being clipped correctly. Here the clipping is probably correct, but scrolling is busted.

Is this a known issue? Blair can you please file a new bug if you still see this issue? I can't reproduce it on my boxes.

I can still reproduce this issue when accessing get add-ons. It appears on all four corners of the get add-ons page for me. BUILD: Mozilla/5.0 (Windows NT 5.1; rv:2.0b8pre) Gecko/20101008 Firefox/4.0b8pre ID:20101008041525 ~B

To be clear, I do not have the scrolling issue. I have the same issue described in https://bugzilla.mozilla.org/attachment.cgi?id=474530 but in get add-ons. ~B

Filed bug 602892. I think I'm going to land this anyway. If we don't get the platform fix then we'll have to tidy this up some other way.

Landed: http://hg.mozilla.org/mozilla-central/rev/ce3d483c2d4e

the bug is still there (on 09.10.10 nightly), if you scroll down the content - the rounded corners get cut off + the garbage appears at top left and top right of the content area if you scroll it up and down. The garbage consist of rounded corners drawn many times.

Filed bug 603120 on the vertical scrollbars being invisible in the AOM after the landing of this bug.

this is not fixed. https://bugzilla.mozilla.org/show_bug.cgi?id=603120#c4

Verified fixed with Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8pre) Gecko/20101023 Firefox/4.0b8pre Dave, I assume there is no need for an automated test?

the fix for this has been disabled in bug 623615

Bug 716439 fixed bug 623615, so we can re-enable this now.
