1445579 - Window controls with CSD overlap pinned tabs when window is resized

Status: RESOLVED DUPLICATE of bug 629388

(Firefox :: Tabbed Browser, defect, P5)

Description

Attachment: screenshot of bug

Mozilla/5.0 (X11; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0 ID:20180313225158

1/ browser.tabs.drawInTitlebar -> true
2/ Pin a bunch of tabs
3/ open a non-pinned tab
4/ resize the window to be smaller

ER:
Space is preserved for the window controls

AR:
The window controls are drawn on top of the tabs

It only happens if you have both pinned and regular tabs open. If you only have pinned tabs or regular tabs open, the behaviour is correct and scrolling arrows appear when you resize the window to be narrower.

I am attaching a screenshot of the buggy result.

This is a known problem with lots of pinned tabs, not specific to Linux.

Indeed I tried in a Win10 VM and Nightly Windows is also affected with the same STR. Since this is a known problem, shouldn't this bug be marked as a dupe to the bug for this issue?

Bug 629388 is the oldest match I could find that's still open:

> 1. Minimize the window so that you don't have to create to many app tabs.

Reporter surely meant "resize the window to the minimum possible with" since you can't work with the window while it's minimized.

> 3. Close and restart the window.

Not necessary (anymore) to reproduce the issue. I think it's safe to dupe to it regardless.
