#Warp Hangs When Resizing

When I resize warp or move to a different monitor, it hangs for maybe a minute. I've noticed this over the past few weeks.

Hi @wanton abyss. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Sorry you’re hitting that. We’ve seen several Linux reports where resizing or moving the Warp window causes freezes, lag, or even black screens—often tied to graphics backends, X11 vs Wayland, or driver issues. A few workarounds have helped others:

  • Try forcing Wayland: run Warp with

  • Try switching GPU backend:

    • WGPU_BACKEND=gl warp-terminal (OpenGL)
    • or WGPU_BACKEND=vulkan warp-terminal
      Note: on some systems OpenGL init may fail; if so, revert or try the other backend. [Contents reverse-stretched]

  • If you’re on X11 and can switch to Wayland, several users report the resize glitching disappears or improves on Wayland. [Window resize glitching]

  • Update to the latest Warp build; weekly releases often include rendering fixes. [Crash on resize]

If issues persist, please share logs so the team can investigate:

  • Run: RUST_LOG=wgpu_core=info,wgpu_hal=info MESA_DEBUG=1 EGL_LOG_LEVEL=debug warp-terminal, reproduce the hang, then attach ~/.local/state/warp-terminal/warp.log along with your eglinfo output on a GitHub issue. [Window resize glitching]

Context: resizing is known to be heavy in Warp because grids are rewritten on resize, which can exacerbate UI stalls on some setups. [Resizing a grid]

If you can share your OS/distro, display server (X11/Wayland), GPU/driver, and whether the above env vars help, I can point you to the closest open tracker.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
