Description of Original Problem: During ffmpeg encoding at regular intervals (10-20 seconds) the computer becomes barely responsive for 2-4 seconds: GUI becomes very laggy, if audio is playing it becomes garbled, video stutters. CPU monitor shows steep drop in CPU utilization. Note, these are not complete freezes, computer still works, just seems to be very very slow for few moments. This makes the computer annoying to use while running a video encode in background. Other than this, the system does not exhibit any other issues.

Troubleshooting: I was suspecting thermal throttling, but CPU die temp hovers around 70 °C (as shown in HWinfo64). I see PROCHOT EXT throttling. VRM MOS average is 98 °C with max of 102 °C. PPT at full 140 W, TDC/EDC at 100%. Maybe the B350 chipset is struggling to support the CPU at 100% utilization?

I have a Debian 11 system. I need to upgrade ssh from 8.4p1 Debian-5+deb11u2 to u3, that package exists. I have different Bullseye system where the packages installed without issues. But here I get dependency failure:

The following packages have unmet dependencies:
 openssh-client : Depends: libfido2-1 (>= 1.8.0) but 1.6.0-2 is to be installed
 openssh-server : Depends: runit-helper (>= 2.14.0~) but 2.10.3 is to be installed

I have oldstable repo in sources:

deb http://security.debian.org/debian-security oldstable-security main
deb http://ftp.cz.debian.org/debian/ oldstable-updates main

I am running out of ideas on why the u3 update won't install on this particular system...

Today I moved final of my cache to a different place (container crushed by a falling tree), but now I realize, how do we avoid collisions that may arise from such move? I simply updated the coordinates on the web (and reworked the puzzle), but that skips the collision check that reviewer would normally make, right?

Whenever I post photos on BlueSky, the result is noticeably less contrasty than the actual image. You can see it in this screenshot, the left is photo gallery, the right is BlueSky, shown in Firefox's split view. The image is standard sRGB JPEG, nothing special. What gives?

I've been using tmux for years. Recently I started to run into an issue where the prefix key (I use C-a in place of the default) suddenly stops working. Any key I press after it gets sent to the underlying pty. This makes it impossible to even escape from tmux. It is possible to open a new terminal window and attach to the tmux session and everything works in that new terminal.

Any ideas what might be going on? It's tmux on Debian 13 (Trixie), the terminal emulator I use is Windows Terminal. This kinda seems to coincide with an update to trixie (previously it was Debian 11 I think).
