P: Crashes when using the filter Lighting Effects

You're welcome Wim. I think v20.0 is sluggish too. 

Thanks to the heads-up from Mark and Rosa I tried the old version (19.1.6) and lo and behold the crash is not there.
Here's what I do in current and previous version of Photoshop:

- Create a new document 1000x1000px 300ppi sRGB 8bit
- Use Filter - Render - Lighting Effects

After clicking OK v20.0 crashes but v19.1.6 does not. Also I have to mention that v20 boots slower and feels a lot more sluggish all around, both apps use the same GFX settings (advanced)

Yes, but it is urgent to produce a solution and not only 2 traces ... Please hurry up, wet your shirts and stop counting the $!

Yes, but this is NOT THE solution, I need new features brought by the latest version, so Adobe, please, quickly a fix of this version, both on Windows that makes PS look like on macOS who does not know how to complete the dynamic object!

Well I haven't apparently but it's easy to install older versions. For those who don't know and are creative cloud members:

- launch the Creative Cloud app
- click the arrow next to Open, then select Manage and then Other Versions
- install v19.1.6 from that list

Exact same issue here Ruth.
And here I thought it was my GFX card!
As for constrains, this reverse hinders workflow but I guess we have to adapt to it.
They could add a setting in prefs though which would solve the problem quickly.

I agree 100%. And I would rather get less-frequent releases of new versions in favor of more stable releases as well. I have been using Photoshop from its beginning. I used to upgrade to new versions with anticipation, now, especially since Adobe went to the subscription model, I upgrade with trepidation. 

Thanks. We have a separate issue tracking that.

For me, the Lighting Effects filter caused a Photoshop crash that not only failed to recover the file but when I went back and reopened it, several layers had disappeared - even though I had saved the file with those layers right before the crash - and the layers that had lighting effects applied were all black. I lost a couple hours of work.

Subsequent tries with Lighting Effects caused strange behaviors, such as layers with the Lighting Effects applied turning black at different zooms. Any attempt to save-as a flattened or exported file resulted in an all-black canvas when opening that file. Sometimes simply moving an image on a layer after applying Lighting caused parts of the image on that layer to turn black.

I worked around the issue by taking a screenshot at the largest zoom that didn't turn black to get a usable image to bring into my InDesign layout. Also, I noticed when applying Lighting Effects, a perspective grid would briefly appear, then a breakdown of the actions would appear in the layers palette until the effect finished.

I am also frustrated by the constrain proportions being reversed. When I don't want to do a constrained scale in the current aspect ratio, I have to hold the shift key to unconstrain the scale. 

On a side note Jeffrey PS CC 2019 displays incorrect processor speed. My Processor Speed should be 3408 MHz not 3MHz
