Re: [orca-list] Orca Hangs When Trying to Read Large Text File in Pluma

[Nolan Darilek <nolan thewordnerd info>]

Gedit definitely does this too. I've occasionally opened larger files 
than normal--maybe on the order of 20-30 MB--and it chokes. I can't 
imagine a problem like this would exist outside of an accessibility 
context. I mean, if Gedit froze whenever someone accidentally opened a 
large file and wasn't using Orca, that seems like the kind of bug that'd 
get fixed, though I can't verify since I need Orca. And my machine is 
definitely up to the task (32 GB of RAM) so I find it hard to believe 
that a text editor would fail to load a file that is less than 1% of my 
total memory.


That said, this does sound like a producer rather than a consumer issue 
(I.e. something upstream shouldn't be generating a11y events just 
because Gedit or anything else opens a large file.)
