        <pre>Seen on kubuntu artful with kde plasma 5.11.3, using the "oibaf" PPA that
provides the latest (git) mesa over the normal distribution one on an almost
daily basis.

Seen both on intel graphics (haswell) and nvidia graphics (Quadro FX 570 with
nouveau).

Since the last week, mesa breaks firefox when compositing is on in the window
manager. Specifically, the overlays that should appear when pressing toolbar
buttons do not appear any more, nor do alert/confirmation dialogs. Note that
firefox does not use the normal system dialogs, rather some overlays right
below the screen element related to them (a button, an element on the toolbar,
etc.).

Reverting to the system version of mesa fixes the issue.

Unfortunately:

1) I have initially thought that the issue was in firefox itself, so I have not
noted down the day on which git mesa started breaking firefox (should be
between 3/11 and 10/11, approximately, though).

2) I cannot bisect, since I rely on pre-built binaries from an ubuntu PPA.

I certainly see the issue with:

libdrm 2.4.88+git1711110630
mesa 17.4~git1711120730

I do not see it with

libdrm 2.4.83 from ubuntu artful
mesa 17.2.2 from ubuntu artful

Neither I was seeing it with mesa/libdrm from git more than about 1 week ago.</pre>
