JetBrains has announced the decision to include support for the Wayland protocol by default in integrated development environments based on the upcoming IntelliJ release 2026.1. Prior to the release, Wayland support can be tested using the EAP builds of IntelliJ IDEA (Early Access Program). IDEs based on IntelliJ can now run directly in desktop environments using Wayland without the need for XWayland. The XToolkit backend for X11 will still be available as an option.
It is noted that since the last testing of direct operation on top of Wayland in 2024, the implementation has increased stability across various compositing environments. servers, drag-and-drop functionality has been added, input methods have been supported, and a natural appearance of window decorations has been ensured. Among the differences in behavior from the X11-based build, the absence of centering or restoring the previous position of some windows and dialogs, the inability to move certain pop-up windows outside the main window, and some discrepancies in window decoration elements (title, window control buttons, shadows, rounded corners) of the active desktop theme have been observed.
The Wayland backend WLToolkit developed for IntelliJ is licensed under GPLv2 and included in JetBrainsRuntime (OpenJDK edition). Over time, the prepared Wayland backend may be integrated into the main OpenJDK codebase. JetBrains is also involved in the development of the Wakefield project, which is developing components to support Wayland in OpenJDK, allowing graphical Java applications to run directly in environments based on Wayland.
