Bridge thumbnails are behaving in a way that cannot be normal.

[W4tsup]

Explanation on what is wrong:

No matter what I do, Bridge seems to generate lower quality thumbnails when it works on them. When bridge has a chance to cache a thumbnail, it will always cache an extremely low quality grainy thumbnail that is nearly unreadable. When I prevent it from caching them, they can look ok for a little bit, but inevitably (when I click on them or when it decides to generate thumnbails for a folder), it will cache and extremely bad looking thumbnail.

I am attaching 2 example files, one of them is the thumbnail before it processes it, and the worse looking grainy one is after the file has been clicked on. This just cannot be how bridge is intended to process thumbnails, they look incredibly bad.

Note: This is also happening in the preview window if it is set to certain settings and reduced to a lower viewport size.

How I can reproduce it:

I use the zoom hotkey on the folder window and it will reload all of the thumbnails into a much more viewable thumbnail, after I click on one it reduces the quality significantly and I need to zoom again to reproduce.

Hi, @W4tsup, Forgive me for asking the obvious, but what are your settings for Preview Quality and Thumbnail Generation? The defaults seem to work well for me and I've not observed your (obviously) poor quality thumbnails.

 

[W4tsup]

Same as yours, but honestly I've tried every combination, nothing in the actual thumbnail settings fixes this. I have done a complete system reinstall from scratch and I've nuked all of the photoshop/bridge/adobe preferences and rebuilt them from nothing and I cannot figure out why they look so bad.

[gary_sc]

OK, so let's back up. 

What brand/model is your computer?

What is your OS (and what release)?

(Note: I'm a Mac guy so if you're a PC user, I may have a limited amount to offer, and if you're one of those folks who build their computer from scratch, I cannot help at all! (LOL))

[W4tsup]

I built my own computer, Windows 11, this issue has persisted through multiple reinstalls of windows and a replaced videocard, motherboard, cpu, and ram. I'm not sure you'll be able to help on this one, I'm fairly sure this is a bug with Windows 11.

[gary_sc]

Yeah, you're out of my league. 

Do you have any connections with others of your computer expertise who have the same build and general configuration who also have Bridge to compare notes with? 

Also, please put this same question/issue to https://adobebridge.uservoice.com/ because that site is viewed by Adobe and they need to be aware of this situation. 

Good luck!

[W4tsup]

I'll go ahead and toss the feedback up there, I actually don't have anyone I know that uses bridge. I'm a digital artist and most of the people I know have switched over to clipstudio and the ones that do use photoshop don't use bridge to navigate through images. I feel like it's a windows 11 issue, but I could be wrong, I have seen a couple other people on the internet complain about this problem when googling so there might be some common denominator in our system configurations.

To be clear, one day my thumbnails looked fine, then they just weren't again and have never gone back.

[gary_sc]

Yes, but if Adobe does see that, THEY have machines with W-11, and they can look for causes. I can't. It shouldn't be doing that.

Good luck.

[W4tsup]

Thanks, I've submitted the bug, hopefully it gets seen by someone!

[EugeneMolotov]

Thanks! It was not so obvious to me.

Hi W4tsp,

Thank you for your feedback.

Could you share the following details so that we can understand the issue

1. Bridge Version

2. Are you facing this issue with any specific file type or all files?

3. Could you share the sample files with us at sharewithbr@adobe.com  

Regards, 

Bridge Team

[W4tsup]

Absolutely:

1. Bridge Version is 13.0.3.693

2. I believe it's with all file types, I checked PNG, JPG, PDF, PSD - all have pixelated image caches.

There are however a few specific files that do not get pixelated, I'm not sure why. It could even be pixelated and I just can't see it. I'll include various examples in the files I send over.

3. I'll send them over right away.

[W4tsup]

Just confirming that I sent you the files over, hopefully someone spots the same issue I have.

[krnirmalkr]

Hi W4tsp,

Thank you for your response. 

We have received the sample files that you sent. 

Could you please help us with the following information about the issue? 

1. What is the system scaling and resolution that you are using? 

2. Can you provide the information of the monitor that you are using to preview images.

Regards, 

Bridge Team

1. I run multiple displays, all 4 monitors experience the pixelated previews/thumbnails issue.

All 4 are running 100% scale, the resolutions are 2560 x 1440, 2560 x 1440, 3840 x 2160, and 1920 x 1080.

2. My primary working display is the 1920x1080 display monitor, but one of the 2560x1440's is set as the system main display. As for the monitor informaiton, the one I am working on is a Huion Kamvas 22 plus, a tablet monitor.

Let me know if there's anything else I can do to help figure it out, I could display the issue live if it'll help.

Just an update here to anyone who might care, Adobe have contacted me and I shared a remote session showing them the issue. They were able to reproduce this on their own machines.
