P: Provide support for Linux

Kde has label and keywords feature in all environment. brfs format stores it eficient and securely. Zfs beats all ideas a mac/win user can have over a filesystem. This is cause i switched completely to freeBSD. memory caching, log caching, data caching, 1 nvme and 32G ram speed up all transactions to
100-500% (it depends is the storage volume is a raid-ssd or single Hdd, of course)

Lightroom replacements: darktable, rawtherapee, darklight... for batch processing imagemagick beats all know software and is integrated completely in the system.
PS: Krita. Gimp is still crazy module GUI with thousand of panels flying like bees.
Premiere: Davinci
AE: Davinci, and blender
illustrator: Krita, Inkscape

Maya, Openshot, kdenlive... a lot of really powerful software

tools for compress: the google algorithm Gueztli + mozpjeg can compress a 100% qual jpg sized in 1M to a 300kb image without any visual lossless.

Advanced users: I reccomend FreeBDS with root in zfs and own compiled kernel. I love Debian too.
Occasional users: Arch Linux, Debian, Fedora, OpenSuse, (formatted with LVM or zfs)
noobs: Ubuntu studio, Fedora design suite, Mint or manjaro

Adobe don't loose the train! Forget macintosh, is falling in the ios abysm. Microsoft, nvidia, intel and GNU-Linux/BSD are alling at last!

Try Rawtherapee 😉 . Darktable is full of bugs and quite slower. But... masks. Rawtherapee need to implement that.

Pretty big deal for a lot of people using Lightroom.  Far more important I would think than a lot of the "tweeks" that are currently getting added.  Please consider!

3 years down the road. Any news on this? This would really really be a very valuable bug to fix (notch notch wink wink).

Thanks for the consideration!

Yes! Thank you Jeffery. I don't have that problem, but others as you may have read. Most are not fixed. Some seem to be related to presets, discovered by reading this forum, but when PS signed out and then back in the presets are gone, meaning I have to start from scratch. I'm not expecting any assistance in this posting, but I wanted you and others to know that this "Family" is a good place to discover answers and new things. I get distracted with all the advice. Good Luck! 

thanks Jeffrey, I hope it is resolved soon:)

There is work being done for the lag with rulers shown.

after searching further I found these two threads:

https://feedback.photoshop.com/photoshop_family/topics/photoshop-cc-2019-healing-brush-clone-stamp-t...

https://feedback.photoshop.com/photoshop_family/topics/ps-cc-2019-slow-performance-overall-slow-redr...

Obviously, there are many performance issues with cc2019. It's a mess because there are several possible reasons and it seems Adobe doesn't know which one is causing the problems. 

Turning off the Ruller makes everything smoother.

I'm not on OSX Mojave, so I'm not sure if the other solutions mentioned in the threads are concerning my setup.

Still trying to work with cc2019 but probably going back to cc2018 soon.

For starters I'm using Windows and don't have this issue. I'm replying because I am having a bunch of issues and many of them are not going away. What has happened frequently is a 'preset setting' has been changed (I didn't do it) and often after I close the application. Sometimes I don't where to look for a preset, I'm not happy. Good Luck! 

now i made the same test on my MacBook Pro (Late 2011) 16GB RAM running on latest OSX Mojave 10.14.5. Experiencing also tha same issues. CC2019 feels in general more sluggish and with the same jagged panning compared to cc2018. Obviously CC2019 needs more Recources?
