352729 - tab labels don't fit into tabs at larger font sizes

Status: RESOLVED DUPLICATE of bug 350194

(Firefox :: Tabbed Browser, defect)

Description

[Myk Melez [:myk] [@mykmelez]]

If I increase the size of the application font on my Ubuntu GNOME desktop to 13px, the labels of unselected tabs jut out one pixel above and below their tabs.  If I increase the font size to 14px, the selected tab also acquires this appearance glitch.  At larger font sizes (16px and up) the labels jut out even more.

This could be related to bug 352303, although I can't reproduce that bug.

To fix this, the tab strip's XUL might need to be reworked in ways similar to how the endcaps were reworked for bug 348138.  The tab endcaps need to know how big to scale themselves.  (Note: the tab strip controls [scroll buttons, all tabs button] need to know this too; they don't currently scale correctly either.)

There are really two problems here:
(1) make all the UI elements in the strip scale big enough (tab endcaps, controls don't currently)
(2) make sure the placement of the controls against the bottom strip is correct (currently tab middles overlap the bottom strip when larger than the default).

Note that this was not a problem in the native tab controls 1.5 used, so it is a regression in Firefox 2.

cc:ing folks who should know what we're likely to be shipping with.

myk, there is a bug about tab problems at high DPI, which is the same issue, I think.

see bug #350194

yes, this is a known regression from 1.5

Hmm, indeed, this is really a dupe of that bug.  Thanks for the tip, Seth!
