[Bug]: batch images disappear right after generation

[askAvoid]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

images generated in batch (count or size >1) disappear from the screen ~1 second after generation. they are still saved to the output directory, however.

single images remain on the screen and can be interacted with.

Steps to reproduce the problem

generate txt2img in batch, either batch count or batch size of 2+

What should have happened?

the generated images remain on screen and can be interacted with

What browsers do you use to access the UI ?

Mozilla Firefox

The program is tested to work with torch 2.1.2.                                                                              
To reinstall the desired version, run with commandline flag --reinstall-torch.

I feel like you might have Do not show any images in gallery enabled but I can't know because if this is the case as

Sysinfo
Not really sure it's relevant here.

and it is working in 1.9

[askAvoid]

Is the default behavior not to show images? Because that would surprise me, and I did not explicitely change the setting.

After a few hundred gens, the problem seems to only happen 4/5 times, the other 20% the gallery is shown as expected. So this feels like a bug than a feature option.

no the default is to show (Do not show any images in gallery disabled)
but accidental click does happen from time to time

only happen 4/5 time

that sounds more like a bug now
but with any bug we first need to recreate the bug in order to be able to fix it

and this

is not helping
Sysinfo contain lots of information including information that we can use to try and retreat your setup

This happens on a brand new machine I built as well. 2, sometimes even 4, images can render in a grid just fine. But if I push it to 6 or 8 per batch, the images generate but just do not show up in the UI.

Same problem for video diffusion.
