I'm working with a custom form created with the drag and drop designer and the bug happens in the attribute table form view and in the value relation widget. I'm not exactly sure how to describe the problem so please bear with me.

If I have record A highlighted and then click on record B which has no photo attribute defined(or if I add a new record), the thumbnail from record A is still displayed. In addition, If I click on record A again the thumbnail is replaced with what looks like a zoomed in, pixelated thumbnail. I also get pixelated thumbnails randomly when switching between records and I haven't been able to figure out any pattern. This seems to be fixed in Master, and I'm hoping this can get fixed in 2.14 for the LTR.

I have tested using the 2.14.3-24 nightly release on Windows 7.

Which widget are you using?
Photo or External Resource?

Are you able to test on current master? I believe I fixed this during the 2.16 cycle, but from memory it hasn't been backported to 2.14. If you can confirm that it works correctly in master than I'll see if a backport is suitable.

Matthias- I am using the photo widget.

Nyall- Yes, I tested in Master and everything worked splendidly. I was hoping to get it fixed in the LTR, if possible. Thanks!
