Re: [orca-list] Sluggishness in Orca



I am using Slint64-14.2. with some packages upgraded.

I just tried with Orca 3.31.1, no lag.

Best,

I am puzzled, as when doing the same thing I observe no lag

I will upgrade to 3.31 if I can do that without upgrading
the dependencies and see what I come with

Hi,

It's when I tab into the voice type settings panel. So, I press caps
lock+space, right arrow to voice tab, then press tab, and it lags
right there.

None of the other panels do this.

I'll see if I can make an audio recording if it would help.

But it's definitely noticeable. I do have the tlp battery saving
utility installed, but this was the case when I was using Orca 3.28 as
well and it did not lag like this, so I'm quite certain it's an issue
recently introduced in Orca.

Thanks,

Brandon

Hello,

there several settings accessible from the Voice tab.

Which one are you using when you get this lag and in
which context?

I ask because the only case where I get a lag (and I know why)
is when choosing an espeak-ng voice in the Person drop-down
list if the variants are enabled in Speech Dispatcher.

Hello,

I can still definitely reproduce the lag in the voice type settings
panel. I just installed Orca master after making sure it was
completely up to date and it's still happening.

Thanks,

Could this possibly be fixed? I do notice a slight lag, less than a  >
second, as soon as the preferences window opens, but the voice tab is

running smoothly here. So this one is either not affecting me, or has

been fixed. I can't tell for sure either way. > # 2. Orca really seems

Confirmed.
