Re: [orca-list] a couple of weird issues with orca's flat review, and changing labels

[Peter Vágner <pvdeejay gmail com>]

Hello,
I have always assumed this is a trade off between excelent performance 
and excessive probing which may impact it.
I am on gnome 3.14, usually progressbars are not suffering from this but 
labels, buttons, web content and maybe others are.
Fix is to alt+tab away and then back.
The most easiest way on how to reproduce this is to copy a large file 
from or to a network drive. Nautilus, pcman fm or any other file manager 
of your choice will report current progress by increasing value on a 
progress indicator. This can either be seen when progress announcements 
kick in or with flat review. The copying dialog will also contain 
approximate estimated time displayed on a label. By using the flat 
review we can see progressbar is updating. Label is also updating but 
orca is not seeing updated content and in order to update switch to 
other windows and then switch back is required.

Greetings

Peter
