Keyframe for Video-speed causes black video on hardware-rendering

I added some key-frames to adapt the speed of a video inside a sub-sequence.
When I use this sub-sequence inside another sequence where other objects (e.g. an image) are assigned in front of this sub-sequence, the sub-sequence ends before expected (black video). when switching off the hardware-rendering (project-setting: Renderer=software only) it's working correct. With Renderer=GPU it fails. I tryed out this with two different graphic-cards (e.g. "NVIDIA GeForce RTX 2060") -> same problem on both GPU's!

It's reproduceable with my sample-project "time-key.prproj" but it can not be attached here because of: "Der Inhaltstyp (text/plain) des Anhangs time-key.prproj.txt stimmt nicht mit dessen Dateierweiterung überein"???
