VSE: Playhead traversal during playback does not update position for jump to start/middle/end of strip #90390

System Information
Operating system: Linux Mint 20
Graphics card: NVIDIA G92 [GeForce 9800 GT]

Blender Version
Broken: 2.92.0 / 3.0.0-alpha+master.ede1ce6e9a5b-linux.x86_64-release
Worked: Unsure

During playback, the jump back to start/middle of strip and jump forward to end/middle of strip functions do not operate correctly.

  • When jumping BACK to start/middle, the playhead springs forward again immediately to continue playback.
  • When jumping FORWARD to end/middle, the sequencer preview will pause on the resultant frame, while the old vector of playback seems to continue invisibly in background. Once this invisible playhead reaches the new/paused frame, playback comes to life again.

Exact steps for others to reproduce the error

Note: I had already made the video before I realized it's not technically a bug, but I've lumped a note in this video posted here as well that during playback, quickly pressing "previous marker" key seems to only allow something like a 0-frame window to press it again and continue moving through the markers. So it's basically impossible unless you hold the key until it repeats, which is a much less controllable usage. I've already posted this on the Right Click Select forum now.

Can confirm, I think this would be nice to resolve, even though it may not be bug technically. So will check how this can be resolved and if this proves to be difficult I may classify this as known issue
