HTOP on Debian 13 N/A Values for (CPUD%), (IOD%), (SWAPD%)

[Tay-lordd]

After the upgrade to Debian 13, all values for (CPUD%), (IOD%), (SWAPD%) are missing

@Tay-lordd: Tried showing these columns as sudo htop?

[Tay-lordd]

Correct. Root user or any other unable to see values

I'd like to work on this issue, I have a Debian 13 server but I can't seem to reproduce the bug.
Would you paste the output of cat /etc/os-release and uname -a here?
Here's an example:

➜  ~ uname -a
Linux sw-dev-debian 6.12.63+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.63-1 (2025-12-30) x86_64 GNU/Linux
➜  ~ cat /etc/os-release

Htop on a Proxmox host does not show the CPUD, etc. values (shows as “N/A”) along with a separate Proxmox Backup Server machine. After the upgrade from PVE 8 to PVE 9 (Debian 13) and PBS 3 to PBS 4 (Debian 13) the values stopped showing. I have a Debian 13 VM shown below that does not show the values as well. I have an Ubuntu VM and Open Media Vault VM (Debian 13) that do show the values.

Does https://github.com/torvalds/linux/blob/master/tools/accounting/getdelays.c work for you? (as root, delay accounting is not accessible to unprivileged users).
