I'm obviously not the OP but I'm just about to reset my preferences again after having only done it about a week ago. I'm running LrC latest version and fully up to date Windows 11. Anecdotaly, I haven't kept a record, I'd say the quality of Lightroom is getting worse. I've been a Lightroom user now for about 10 years. Here's my latest experience leading me to think I need to reset preferences:
1. Imported 23 new16MB RW2 files from my GM5.
2. From grid view press the D key to go to Develop module
3. Start to apply some basic adjustments to some photos.
4. After a very short time, maybe 5 minutes or so, I start to see the following behaviours:
a. Pressing the "\" key results in the Develop window just showing the background colour, no image is shown for the "Before" although the "Before" status message is displayed.
b. Zooming in does nothing in the main Develop window although the zooming in action is displayed in the small navigator thumbnail i.e. the zoom outline is shown there.
c. From the Develop module pressing G gets me to the Grid view but no images are shown, just the background colour. Using the Thumbnail zoom control makes no difference, still just the background colour is shown. Pressing E takes me to the Loupe view for the currently selected image (although I can't see in advance which one that might be). It is displayed correctly. Pressing G again does not take me to Grid view but just displays the image in Loupe view. Note that the icons at the bottom left indicate that I have navigated to Grid view.
d. Whilst in the Deveklop module the processing ball constantly runs. Swapping between different modules and back to Develop and the processing ball is still spinning.
e. In Develop module moving to the next image by pressing the right arrow key results in the next image being displayed in the Navigator window but the main develop image stays the same.
f. I often get the not responding message in the title bar (not sure if that's the right terminology) and the spinning ball as well as an overall slowing in performance. I often have Task Manager running in the background and looking at the resourves in use when LrC seems to be "busy" shows minimal processor utilisation, <10%, overall memory usage at <75%, negligible/no GPU processor utilisation, < 5%. I have no idea what LrC is up to when it pretty much grinds to a halt. It certainly doesn't seem to be using an excess of resources.
It would be easy for me to continue to list the poor experiences I am currently enduring with LrC. I have always had "quirks" in the way that Lightroom runs across multiple laptops and operating system versions. For me, the latest iteration of LrC is really poor, quality wise. I run other photo editing software and have no such issues with those e.g. DxO Photolab 4, OM Workspace (although slow has none of the other issues I encounter with LrC).
For reference, I run a Surface Book 2, i7, 16GB RAM, NVidia GTX 1050 and Windows 11. I've been running LrC on this machine for almost three years and at the moment LrC is the worst it's been quality wise. I always keep my OS and applications up to date. Most of what I have described above has only been happening in the last few weeks.
