System Information

Operating system: Linux-5.15.0-76-generic-x86_64-with-glibc2.35 64 Bits, X11 UI
Graphics card: NVIDIA GeForce RTX 2060 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 525.125.06

Blender Version
Broken: version: 3.6.0, branch: blender-v3.6-release, commit date: 2023-06-27 08:08, hash: c7fc78b81ecb
Worked: (newest version of Blender that worked as expected)

Short description of error
When pressing play on the timeline the values in the spreadsheet are not updated except when the mouse enters/leaves the area.
Using the arrow keys to go one frame forward/backward does update the spreadsheet.

Exact steps for others to reproduce the error

Open the attached .blend ( create a GN tree changing some attribute in your scene)
Press Play. Observe the spreadsheet is not updated

Moving the mouse over the spreadsheet, or back out again makes it update
Pressing the left/right arrow makes it update as well.

I can understand the spreadsheet not updating during playback for performance reasons, maybe. But as soon as you press pause I'd expect it to update.

Hi! Make sure you have "Spreadsheet" option selected in timeline playback options. This option is added for performance reasons. Enabling the option did solve the issue.

Will close the report since this is not a bug with blender. But I think we need to better clarify this in the manual or somehow hint it on the UI.

I'd still expect it to update after you've pressed the pause button.

As it is it now shows stale data when the animation is no longer playing. Which doesn't happen anywhere else in blender I think, And also is very confusing.

You mean it's showing data from the previous frame when pause button is pressed, even when you enabled that option?

No, when I enable that option everything works.
what does not work, and is somewhat unexpected imho is:

press play
press pause

Spreadsheet shows info from before you pressed play. As soon as you move the mouse into or out of the spreadsheet area it updates to the info of the current frame.

I'd expect the spreadsheet (even without that option) to be updated once when the pause button is pressed. Other areas of blender which don't get updated during playing work the same. They get updated as soon as you pause/stop the playing.

@lichtwerk fixed/added this option: #108002

Guess further fix is to redraw/refresh the spreadsheet area when play animation is toggled?

Could be that the missing update also came with d8388ef36a ?

This does make sense... I would prefer it to update on pause, but adding yet another option for this seems to be overkill...

Probably that causes it. But I'd think a redraw of the spreadsheet area could be triggered without a new depsgraph evaluation. As seems to be implied for that patch, though I guess that patch forgot to trigger the spreadsheet area as well.I'll see if I cna find the time to find out how this works. My guess would be just triggering a redraw of the spreadsheet area should be enough, but I don't know much (yet) about the gui code.
