What a surprise! Pentax annouce a delay in the availabilty of the teased 50mm f/1.4. When will the delay in the availability of the long-overdue wide angle zoom for APSC bodies be made? Maybe Pentaxians should ask either Tokina or Tamron when these lenses will be launched?

Thanks to everyone who posted replies.
Thank you Isimpkins... after you suggested that this might be a GPU issue, I installed LR on a completely different PC and found no corrupted files. After a process of elimination involving several tests and component permutations, I think that you are spot on in diagnosing "yet another Graphics Processor related issue". I will discuss this this with the Adobe Support Team. THANK YOU!

P.S. If you have any links relating to "yet another Graphics Processor related issue" I should be grateful if you would post them, JeaPea

Bridge (and Lightroom) both write any editing adjustments and update the embedded JPEG preview to the DNG file envelope. I have heard mention that these apps may be corrupting the TIFF headers (DNG files having a similar structure to TIFF files

Thanks for your comments. These Adobe are supposed to write any changes and update the DNG file envelope thus avoiding the need for .xmp sidecar files. This corruption only happens with these two apps and not with other software that I have mentioned. So far, I have been referred to Adobe's third tier of Support. They can replicate the issue but are currently unable to identify why or offer a solution. The issues have only happened since updates to both apps from September 2017 onwards and would seemingly point to Adobe updates ince then.

The DNG files I am using are those that are natively produced by the Pentax bodies I own. They are "added" to the Lightroom catalogue or viewed dierctly from the folders that they are stored on an internal hard drive...

Thanks for your comment. However, the DNG format is an Adobe file standard and Lightroom and Bridge should (and write) to these as they would any DNG file whether it results from a conversion or is generated by cameras such as Pentax or Leica

Am I the only one? Being a Pentaxian it often feels like one is participating in a minority sport. Please read on and hopefully help a true believer...
Lightroom and Bridge are corrupting my DNG raw files as generated by four Pentax DSLR bodies, i,e. K-5 II, K-3, K-70 and Pentax K-1.
I can open and edit the DNG raw files from these Pentax cameras in Pentax DCU, DxO Photolab, Topaz Studio, and Skylum Luminar as long as they haven't been previewed in Lightroom CC Classic and/or Adobe Bridge CC 2018. Once they have been previewed, let alone edited, in Lightroom and/or Bridge, they become unusable in other software applications.
Upon previewing them in Lightroom and/or Bridge, both the thumbnails and image data become unusable. The previews have either a weird posterised look or have large sections covered in red diagonals on a white background.
Has any other Pentaxian experienced this? Better still, does anyone have a solution to this issue?
Thanks in anticipation of your help.

I took delivery of the dedicated Kirk L-bracket two weeks ago after rejecting the equivalent product from the Really Right Stuff. They are both really well made and have lugs that securely locate with the camera;s baseplate... There is no twisting when using the camera in portrait orientation, even with a heavy Pentax 15-30mm lens attached. I decided upon the Kirk bracket as it allows full access to the ports on the camera body side. Now when I orientate the camera vertically it is centred over the tripod head and column provoding a secure platform. Unfortunately I don't think it would with a power grip. Hope this helps.
