Lightroom: TIF files (Silver Efex Pro) cannot be edited in LR 4.x - continuously redraws

Generate a TIF file from Silver Efex Pro, launched from Lightroom. Bring the TIF back into Lightroom, and edit it (crop, or add a brush). It is impossible to edit, as the program (LR) keeps refreshing the image all of the time. This is a problem that was introduced in LR 4.x and has yet to be fixed. It is a very bad problem, which didn't exist with previous versions

Do you mean it still occurs in LR 4.2 and originally occurred in LR 4.0?
If you re-export the TIF to another TIF in LR w/o making any modifications does the new copy of the TIF also have the problem?

It occurs in every LR 4 version. It sometimes occurs with PSD files as well, but most reliably with TIF files. Yes, any TIF file (I've tried also uncompressed and compressed). This is the Mac version.

I've had this happen a few times on my PC with any sorts of files, since before LR4, but it usually clears up after I restart LR or restart my computer. I've imagined it happens either because my video drivers are a little iffy, or that my photos and LR catalog are contained on an external USB drive.

Does it happen if you make a completely new catalog and import just one of those TIFs into it? In case it has to do with some preview-cache corruption or LR3-to-LR4 catalog conversion issue.

Yep, happens then too. I was hoping the latest 4.2 update would fix this, but no dice. Never happened with 3.x versions, so its really annoying! Thanks for the comments though.

Do you have automatically write to xmp turned on in preferences? Do you see the same if you turn if off?

Brilliant Victoria! That was it. Thank you. Kind of a bad bug Adobe... hope an update fixes this.

With TIFs and PSDs (and JPGs), XMP data is written to the image-file, itself, instead of to a side-car as with RAW files.

I wonder if something silly is going on where if the XMP data takes longer than a second to write to the file, that LR sees the change in timestamp as an update to the file and writes the data, again, and if it always takes more than a second then the process will repeat forever.

The reason it would take longer than a second would be that the files are so large as compared to a tiny XMP sidecar for a RAW file or smaller-sized JPGs.

You may also find that flipping to another photo to a few seconds and then flipping back again before editing (i.e. after it comes back from Nik, then flip) may do the trick even with auto write turned on.

I'll try that, but I've seen this when just opening the app and dealing with a TIF file straight away. But I've also not seen it happen there too!, so it probably is some kind of timing related issue. I've lost enough time with this problem, so I'll just leave the XMP turned off until its fixed though :-)
