Games are games, work is work. I disabled every animated transitions in my desktop UI. Elements appear instantly at full size in the place they rest and disappear instantly.

Reasons:

1) I'm doing that thousands of times per week, I know what's going to happen

2) It's my desktop, there is no one else who might be puzzled by a non standard behavior

3) It's faster.

By the way, it is a GNOME desktop on Debian 13.

Oops, I lied. I was about to click on Reply and I realized that the bottom panel (which on a standard GNOME is at the top) is on autohide with a short transition. Maybe because it's the only transition that I activate with the mouse pointer: I hit the bottom of the screen and while it's traveling the last pixels the bar starts sliding in. It's very fast.
