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).
