I'm on v23 of Premiere and noticed on inconsistant times if I add new media to an empty sequence and drag it all the way to the start it will keep 1-2 frames of space between the first frame of the timeline and when the media starts. I noticed if I zoom into the timeline it then is able to move to the start. I'm running it on windows 11 version 21H2, procssor 12th Gen Intel(R) Core(TM) i7-12700 2.10 GHz, it's a lenovo build with 16gb installed ram. I noticed a new update for premiere today so may be fixed but didn't see documentation mentioning this bug so putting it out there and will update this if I continue expereincing issues with v23.1. It isn't a big deal because shortcut keys seem to avoid that and zooming in on the timeline seems to let it move freely aswell. Just something I recenly noticed.
