System Information
Operating system: Linux-5.18.10-76051810-generic-x86_64-with-glibc2.34 64 Bits
Graphics card: AMD Radeon Vega Frontier Edition (VEGA10, DRM 3.46.0, 5.18.10-76051810-generic, LLVM 12.0.1) AMD 4.6 (Core Profile) Mesa 21.3.5

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2022-12-12 17:15, hash: 54aec4629e
Worked: (newest version of Blender that worked as expected)

Short description of error
In the Video Sequence Editor, when moving strips that have the speed factor different than default 1.0 the strips seem to glitch so the start and end of each strip fluctuates.

Exact steps for others to reproduce the error
New file
Go to VSE
Add a movie strip
Use "K" to cut the movie strip a few times (so you have maybe 10-15 strips)
Select a strip, go to the Time panel and change the speed factor to 1.5
One by one, do the same with all the strips (perhaps giving them various values between 1.1 and 1.5)
Move each strip up against each other, so there's no dead space between
Select all of them and move them around...
{F14115112}you will see the length of each strip fluctuates

For now I can use double precision instead of float. Retiming tool does not have this issue, but that can be done in 3.6 only.
