Revert "linux/x11: Reduce input latency and ensure rerender priority (#13355)" (#13465) 
This reverts commit f69c8ca74e after it
has already been partially reverted in
https://github.com/zed-industries/zed/pull/13458.

Why the revert?

The changes in that commit/PR fix one type of problem — dropping of
frames when being blasted with input events — but trades it for another
one that I can't explain yet: when the system is under load, then input
becomes _laggy_ and input events seem to be delayed.

Two examples of how that shows up:

1. When the system is under load* and you hold down the `down` key to
scroll, then lift the finger, the cursor stops sometimes. If you then
produce another input event by jiggling the mouse cursor you'll see more
`down`-key events coming up and the cursor moving down. It feels as if
the event loop is not being woken up even though there are still events.
I suspect it might have something to do with XIM, because if it's
disabled, it seems as if problems become less severe.
2. When the system is under load* and you click-and-drag a selection in
the editor, you can see how the selection is delayed and takes 500ms-1s
to catch up to where the cursor is.

* system under load: start Zed, then in another terminal window create a
release build of Zed, for example.

With the changes reverted, the failure mode looks different: we skip
frames. But that, I think, is the better of two bad options, because
skipping frames means that you see what's happening vs. input events
seemingly still coming in seconds after you stopped using the keyboard.

Zed

CI

Welcome to Zed, a high-performance, multiplayer code editor from the creators of Atom and Tree-sitter.

Installation

You can download Zed today for macOS (v10.15+).

Support for additional platforms is on our roadmap:

For macOS users, you can also install Zed using Homebrew:

brew install --cask zed

Alternatively, to install the Preview release:

brew install --cask zed@preview

Developing Zed

Contributing

See CONTRIBUTING.md for ways you can contribute to Zed.

Also... we're hiring! Check out our jobs page for open roles.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
