Since you have such a nicely reproducible case, do you have time to try some experiments? I see earlier in this thread that you simplified your localhost file and it seemed to help. Was that a false success? I suspect it might be, since the theory was the problem was triggered only for very large localhost files. Have you tried some of the earlier thread suggestions? Specifically: 1) Disconnect from the internet (just unplug) 2) Disable 3rd party plugins (Look for them in your Photoshop system report) 3) Disable some specific plugins (see post 92): In Photoshop 2015.0.1: Preferences>Plugins>Enable Generator = OFF Preferences>Plugins>Allow Extensions to Connect to the Internet = OFF Preferences>Plugins>Load Extensions Panels = OFF Preferences->Technology Previews>Enable Design Space Preview = OFF These are all temporary changes of course, and the only purpose is to see if we can narrow our focus of where to look. If things get dramatically better with all these things off, then we can enable the above one at a time, starting with internet access, and repeat the tests. If the problem still occurs with all those things disabled, the next thing to eliminate is various drivers: 1) Display - make sure you are running the latest version 2) Hard Drive - try to reproduce with no additional drives attached; just the boot drive with 3) USB devices - external hard drives, CDROM/DVD burners And anything else that you can think of that (firewire cards, other PCIe cards, SATA drivers, thunderbolt, etc.) The reason I am looking at these is because of the cursor jumping behavior; it seems like something on your system with the ability to do a high-priority interrupt is taking control and locking up. Briefly. Operating system events (e.g Mouse-moved) do not seem to even be getting to Photoshop, as evidenced by the fact that your enabled menu items do not even highlight as the curser tracks (jumps) over them. We'll want to identify the drivers that are actively running on your system and try and temporarily disable them, if we can. Or as many as we can. Running the tests in Windows Safe-mode should be a good way to do this. I know I'm rehashing items that were previously touched on in this thread, but I don't know if you've looked into them yet. And my instincts based on what I saw in your video are leading me in that direction. (Also, for reference, a wiki page we maintain with most of the things that have bitten people in the past: http://blogs.adobe.com/crawlspace/2012/07/photoshop-basic-troubleshooting-steps-to-fix-most-issues.html Most of these suggestions probably don't apply of course, but it's still useful to review.) Finally, do you have any other applications running in addition to Photoshop, like a web browser, e.g. Google Chrome, or or background processes, e.g. antivirus? If so, what are they? Thanks
