P: Add the possibility to disable full image preset preview

Amen

Thanks for being here, Rikk, and I hope you don't mind if I laugh a little at the phrase "unintended consequences" because that is precisely why this config.lua file is so appreciated.

Even if my laptop could perform the render instantaneously, I don't want my main image switching its presentation without my intentionally choosing it. Looking forward to Adobe correcting the unintended consequence of a mouse movement.

Greetings all, 

I see a couple of users have posted a workaround involving the use of a 'config.lua' file to temporarily disable the current preset preview behavior. 

Please do not consider this a permanent fix for this issue. This was a temporary rough workaround for test purposes only. Use of a config.lua file to modify behavior can have unintended results and may cause issues with future installations. 

For those of you who've contacted me via email regarding special access to a preliminary update for a permanent resolution of the issue, we expect to have that available for you to review shortly. 

Thank you for your patience. 

This feature SUCKS... PLEASE turn it off or give us the option, ASAP.  My workflow along with others has come to a screeching halt.  

Can't do 7.2 because it doesn't recognize RAW from the Sony A7-III

Here is the slight modification made for Mac

1. Launch Lightroom Classic CC
2, Chose (top menu) Lightroom>Preferences
3. In Preferences go to Presets tab
4. In Presets click on Show Lightroom Presets Folder button. Open as a new windows
5. In that window click on the Lightroom folder (not the Lightroom CC folder).
6. Go to the link https://adobe.ly/2He219B and download the config.lua file. 
7. Go to the download folder and drag the config.lua file into Lightroom folder in step above.
8. Relaunch Lightroom Classic CC.

The System Info dialog (Help > System Info) should display the config.lua flags entry as shown below, indicating that Lightroom Classic CC is now disabling the live preset preview in the loupe view:

Config.lua-Flags:
Develop.disableLoupePresetPreview = true

With minor differences in OS this works well for Mac!  Thanks, Dallas, you have saved me from DPFF (development preset frustration forever)!

Here's the fix for this problem that was posted on the Adobe forums by F. McLion: 

1. Launch Lightroom Classic CC

2. Choose Edit > Preferences.

3. In the Preferences dialog, go the Presets tab.

4. In the Presets tab, click the Show Lightroom Presets Folder button. The root preset folder opens in the File Explorer.

5. In the File Explorer, navigate into the Lightroom folder.

6. Go to the link https://adobe.ly/2He219B and download the config.lua file. Copy the downloaded config.lua file into the Lightroom folder mentioned in the previous step. 

7. Relaunch Lightroom Classic CC.

The System Info dialog (Help > System Info) should display the config.lua flags entry as shown below, indicating that Lightroom Classic CC is now disabling the live preset preview in the loupe view:

Config.lua-Flags:
Develop.disableLoupePresetPreview = true

I can confirm that this worked for me. I have now also solved my connectivity issue (something 4 of the Adobe support staff over 4 remote sessions lasting an hour each time weren't able to do). The fix? Reboot my router...

Honestly, my opinion of Adobe is so low at the moment that if I was within arms reach of one of the "support" staff I'd have to be restrained from dishing out a bit of my flat palm to the side of their cheek! 

The solution to the preview problem has been posted on the Adobe forums and it works, but now I simply cannot upgrade any of my apps because apparently my internet connection can no longer communicate with their servers to download the updates. Updates get to 3% and then just die. They (Adobe support) literally told me to change my ISP in order to update Lightroom. Can you believe that? 

I wrote on another thread also, but the full screen preview has practically made me hate editing. It's one thing that my laptop fans are screaming and CPU overloading, but also super difficult to compare with/without preset. I need to see the change to understand what a preset does, now I need to move cursor out of the list to see pic without preset. Hovering from preset to preset is not the same as you never see the original in between.

Damn I hate this live preview stuff. Same thing with Illustrator reacting to every typed number in type size for example. Changing type size from 10 to 11 you never see the actual change from 10 to 11, only sizes 10->1->11.
