[Bug 673389] [NEW] Clicking on huge image locks/hangs machine (complete loss of interactivity)

[Paul Sladen]

Public bug reported:

Binary package hint: firefox

Note that whilst I've initially filed this against Firefox, it is a
wider cross-stack performance issue (a single application should not be
able to bring the machine down).  Clicking on the following image:

(27,000✕17,000)

sets the Firefox title, but then immediately locks the machine with all
loss of interactivity.

Ideally Firefox should not undertake activities that are likely to bring
the machine down (such as allocated huge arrays for data that it has not
yet even received) and ideally the rest of the stack down to the kernel
should not let a single application bring the rest down.

** Affects: firefox (Ubuntu)
     Importance: Undecided
         Status: New

** Summary changed:

- Clicking on huge image brings machine to standstill (complete loss of interactivity)
