Old QuickLook "white image" bug still present in Mavericks

If you find two JPEGS with exactly the same dimensions (pixel dimension)...

...and view them in the Finder in list view

...and the two files are adjacent to each other in the list (for example, File1.jpg and File2.jpg)

Then if I press space bar to invoke QuickLook on the files, it will show each file properly, BUT if I use the arrow keys to move between them, then when I move from the second image back to the first image, the first image shows up as a blank / totally empty file.

This message occurs in the Console, but only the first time I attempt to view these identical-dimension files:

3/21/14 2:41:11.559 PM quicklookd[19960]: Warning: Cache image returned by the server has size range covering all valid image sizes. Binding: VariantBinding [0x403] flags: 0x8 binding: FileInfoBinding [0x303] - extension: JPG, UTI: public.jpeg, fileType: ???? request size:16 scale: 1

This only happens with images that are the EXACT same pixel dimensions.

It has happened since at least 10.7, and still occurs in 10.9.2.

I have reproduced this on two separate machines.

Suggest you use the feedback form if you have not already reported it.

http://www.apple.com/feedback/macosx.html

If you have a developer account you can I understand file it as bug.

I too am having this issue. Been happening for a while through all versions of Mavericks.

This issue probably caused by enabling text selection in Quickview.

Try to turn it off by entering following command in Terminal:

defaults delete com.apple.finder QLEnableTextSelection; killall Finder

Thanks, berdimurad. This took care of the issue for me.

I’ve had this issue for some time on my MacBook Pro, but my wife’s MacBook Pro has never had it. I figured it was something I had installed or customized. I think I noticed this back in Mountain Lion, and now we’re on Mavericks 10.9.4.

Thanks, berdimurad. That seems to have fixed it for me. I had enabled text selection in Quick Look via MacPilot a while ago. Turned it off and the blank preview problem seems to have disappeared.

Thx, berdimurad, this fixed it!

Jul 12, 2014 10:51 AM in response to berdimurad

That solved the issue for me too!

Thanks a lot!

Knowing now the source of the problem, just let us hope that is not a vain wish that Apple correct this bug for the "text selection" parameter.

To manage it you can also use ONYX / Parameter / Finder and deactivate the parameter ib it.

Yep I used Cocktail software to achieve the same as the Terminal command. In Cocktail it is under Interface > Finder > then untick "enable text copying from Quick Look", then click the Relaunch button to restart the Finder. Problem was resolved after that.

Of course, it means I now can't use a feature that Finder is meant to provide, that of text copying from quick look which I find very handy, hence I have reported the bug http://www.apple.com/feedback/macosx.html

I thought I knew everything about OS X that was handy to know, but I didn't know that text could be had from a QuickLook pop-up!

Shame it's been the cause for the breaking of the feature, is it an official option?

@Hamper, looks like it's unofficial, I had a bit of a poke around but couldn't find anything from Apple about it, seems to be only hacks and tips pages which mention it. I think I originally found out about it when I saw the option in Cocktail, and ticked it.

I wasn't able to simply delete the file to fix the problem. I had to go into my back up account and make a copy of the file from ~Library/Preferences/com.apple.finder.plist and then move it into my user account. I'm sure you could do the same thing with your Guest User account too.

For me, the problem was caused by making the text in QuickLook copyable. I noticed when I turned on "defaults write -g QLEnableTextSelection -bool true" that the blank Quicklook bug was coming up as talked about in this thread. When I turned it off, (defaults write -g QLEnableTextSelection -bool false) the problem went away.

Using Mavericks 9.4 and still have the problem. Have discovered that if I hit the option key the white screen shows an enlargement and when I let go of option, I get the picture.

This worked for me on 10.10.5
