The issue describes Wayland window capture, cursor telemetry, and .cap import through the XDG Desktop Portal, but names no source files or tests. Start by locating the Linux capture and portal file-picker entry points and their related tests. The work is done when window dimensions are preserved, cursor and click events are captured, and .cap bundles can be selected for import; linked PR #2420 is already open.

Description

On Linux (Wayland), screen recording encounters three significant limitations when capturing windows and managing projects:

  1. Aspect Ratio Distortion: Capturing non-16:9 windows (e.g. mobile emulators in 9:16 portrait orientation) forces the stream into monitor bounds, stretching the window horizontally instead of preserving its native dimensions.
  2. Missing Cursor & Click Telemetry: On Wayland, cursor capture stubbed out with empty events (moves: vec![], clicks: vec![]), completely disabling Cap's zoom/click wave features.
  3. Project Import Failure: XDG Desktop Portal FileChooser does not recognize .cap directory bundles as selectable files, entering the folder rather than importing the project.
Reproduction
  1. Run Cap on Linux under a Wayland session (tested on KDE Plasma 6).
  2. Start a Window recording and select any non-16:9 window (e.g. Android Emulator / narrow browser window).
  3. Notice that the resulting recording is stretched to 16:9.
  4. Notice that mouse movements and click ripples are missing from the preview.
  5. In Editor, try to "Add Clip" and pick a .cap recording folder - portal file picker navigates inside instead of selecting the project.
Additional Context
  • Cap version: 0.6+
  • Operating system, version: EndeavourOS / Arch Linux, KDE Plasma 6 (KWin Wayland)
