Premiere Pro Interface Lag (2018 and 2019)
So far this issue only appears to be happening when working with existing project files made by two of my nine in-house Mac edit suites, editors Ben (Edit 😎 and Andrew (Edit 1), I'm naming them just so you can keep track of which stations I'm referring to. Both culprit stations are top spec iMac Pros with ATTO thunderlinks
connecting to the same SAN storage as all other stations. Premiere Pro, both 2018 and 2019, is having lag issues when interacting with all areas of the interface. Any area I click or attempt a keystroke is problematic. Almost every attempt at clicking or typing induces a delay and or pin-wheel. Initially, the issue occurs every couple of seconds with a pinwheel length of 1-3 seconds. Over an hour or two, the delay/pinwheel length grows and grows up to about 6 seconds, while still happening on almost every interactive or every other interaction. The only temporary fix is to import the most important aspect of a project, the main edit timeline, into a freshly made project file, losing all of my media and bins not already used in that timeline. Any other attempt at importing more than one timeline or unused media doesn't make the temporary fix. This fix is only temporary because the interface lag creeps back, requiring another fresh project import of the timeline. Many times when I close any of the problem projects, a small popup window with a title of 'Run Script Error' is shown with body text of 'Uncaught exception' and an okay button. The lag issue is happening on a second workstation, user Jacy in Edit 7 (iMac Pro, top spec, with the exact same configuration as the iMac Pros that originally created the project files that lag) but the original workstation that created the project files do not experience the lag. Deleting everything (media, generated items, and timelines) from all open projects fixes the issue so the software no longer lags.
The timelines play fine for me in Edit 4 (Nick), they just take a few seconds the start and after hitting the spacebar can take up to 6 seconds to stop. After Effects, Finder, and all other software are having no issues so I don't believe the issue to be our storage I/O or throughput.
