System Information
Operating system: Debian 10 ppc64le
Graphics card: RX580

Blender Version
Broken: (example: 2.80, edbf15d3c0, master, 2018-11-28, as found on the splash screen)
2.90.1-1~bpo10+1

Worked: (newest version of Blender that worked as expected)
blender_2.83.5+dfsg-2_ppc64el

Short description of error
I'm in the compositing window and I have a Viewer node.
The image appears in the background, behind the nodes
When I click play, the Dope Sheet cursor starts moving, current frame is advancing
But the frame displayed in the back of the compositing window remains frozen at the point where I clicked play.
If I manually change to any specific frame, it correctly renders the frame.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Can you please advise if there is already a known issue or if something changed between 2.83.5 and 2.90.1?
Is there anything I need to change in the settings to make the preview live?
If the issue is unexpected then I'll prepare a sample .blend file and submit it here.
