System Information
Operating system: Linux-5.11.0-38-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce GTX 670/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.74

Blender Version
Broken: version: 2.93.6 Release Candidate, branch: master, commit date: 2021-10-06 10:52, hash: 0930a70e81
Worked: (newest version of Blender that worked as expected)

Short description of error
When Prefetch is enabled, changing it's opacity blend_alpha value doesn't invalidate current prefetched frame and display doesn't change.

Exact steps for others to reproduce the error

From Video editing
Create a Text and a Color strip
Add a Wipe effect on these two
Enable prefetch
Change Wipe's opacity
Preview remains the same, you have to move to see the change or refresh_all()

When you say, "Enable prefetch" do you mean Prefetch Frames in the View Settings?
I can't reproduce the problem.

I reproduced this bug in the latest official release, but not the latest daily build, so it appears the bug has been fixed already.

It doesn't seem like a critical issue to backport in 2.93 (Cc @iss)

Please try the latest daily build: https://builder.blender.org/download/

If the problem persists, please let us know so we can re-open the report. Don't forget to mention the specific version you tested again.
