[Message part 1 (text/plain, inline)]

Hi,

Maybe that's just me (or the theme I'm using) but when there is
antialiasing involved, the visible flashing produces rather ugly glyphs.

It is much more pleasing with this patch.  Or maybe, we need a user
custom for it.  WDYT?

(Disclaimer: I have not tried the patch.)

The introduction of new user options which affect the visible bell on
one window system must be attended by comparable modifications to all
the others, which is infeasible inasmuch as other window systems don't
provide straightforward mechanisms for inverting the contents of a
window.

While the last sentence is not directly relevant to the patch itself,
I'm for leaving the code as it is; the present state of affairs has
withstood the test of time, and it would be unwise to change it by
caprice.

You're right and I won't be able to test (or even implement) for other
window systems.  Or why not have a 'x-...' specific user option.

Yes but I wonder if I'm the only one seeing this (I'll try to capture
some screenshots of those flashing).  It might be a just configuration
problem.

I think a proliferation of such options is likely to prove detrimental
in the long run.  There are already far too many.

Sure, please do that.

So here is the top of my window (themed with ef-summer) in neutral
state:

[themed-neutral.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

The same space flashed with current code:

[themed-flash-current.png (image/png, inline)]

[Message part 5 (text/plain, inline)]

Same but flashed with this patch:

[themed-flash-invert.png (image/png, inline)]

[Message part 7 (text/plain, inline)]

Note that this much less of a trouble with no theme and black on white:

[not-themed-flash-current.png (image/png, inline)]

[not-themed-flash-invert.png (image/png, inline)]

[Message part 10 (text/plain, inline)]

I can see that effect here too.  I don't think we need a user option for
this, it just looks like a plain bug that should be fixed.

The current behaviour seems suboptimal, so if it works and there aren't
any other problems with it, then I don't see why we shouldn't install
it.

Let's wait to see if anyone else has anything to add.

Only that follow-ups from this thread always run afoul of the mail
delivery issues my provider suffers from :-(

Please postpone installing this patch until I get around to testing it
on a few X servers besides Xsun and Xorg.

Hi Po,

Did you happen to have time to test this issue on other X servers?
Thanks.
