Use of volatile images (PIVOT-390)

[Greg Brown <gk...@mac.com>]

Hi all,

PIVOT-390 describes an issue with volatile images that several developers have now run into. Disabling the use of the volatile image buffer resolves the problem.

I see two potential solutions to this:

1) Provide a startup property that disables the use of volatile image buffers (and uses standard buffered images only).

2) Drop the use of volatile images for back-buffering altogether.

On my system (OS X), I don't notice any difference between plain old buffered image buffering and volatile image buffering. However, I think it may be more noticeable on Windows.

I lean slightly towards #1 above - what do others think?

Greg

I have already added support for option 1 so it is possible for users to disable volatile images. However, I think it is preferable to leave them enabled by default since this problem does not appear to affect most users, and it does improve performance.

Hi, as Todd I'd prefer number 1, but are we able to ask to users if
the problem happens on many platforms, to see if it's safer to set the
number 2 as default (could be a platform/java combination issue) ?
