P: Color Blend Mode displays wrong colors; sometimes crashes

thx, man! I am specially registered to say thanks!

As mentioned enabling legacy compositing in preferences fixes for me too. Updates immediately after change.  (Windows10 user)

.  All my blue color overlay layers on previously made and reused files were turning to pink.  Other layer styles also seemed quite different or "more strong".    

Please Adobe, Update the Photoshop update to correct this so we don't need to check yet another legacy checkbox every time we install fresh or lose our prefs.    If this was a purposeful change, I think a heads up and explanation of future direction would have been required to all your clients. As this is a significant change if not just a bug.

As always, I appreciate the community who solved this and shared the workaround before I ran into it.

I have the same problem with the hue and color blend modes.  The incorrect color is applied. Windows 10 on an HP Xeon workstation Z230.  Clicking the legacy compositing engine fixed the issue.

Thanks Jeffrey

When I change one layer blend mode, the layout freezes and I have to restart Photoshop. I'm using the new version Photoshop CC 2019.

Engineering is working on a fix for this issue.  The workaround is to go to Preferences > Performance... and check "Legacy Compositing"

When I select an area of an image, and turn that into a solid color overlay, and then change the blend mode to "Color", the colors are wrong. My image is RGB and I have selected filled pixels (not an empty area):

I'm having the same problem with the color blending mode.  Green with a few unaffected stripes.
