Description Zack Melan 2025-02-17 11:26:56 UTC

**Description:**

I am experiencing a desktop freeze when attempting to maximize the Chromium browser by dragging it to the top of the screen.

**Steps to Reproduce:**

1. Open the Chromium browser.
2. Drag the Chromium window to the top of the screen to maximize it.
3. As soon as the mouse cursor hits the top of the screen, the desktop freezes.

**Observed Behavior:**

- The desktop freezes completely.
- Using SSH from my phone to access the PC, I observed that `kwin_wayland` is using 100% of the CPU.

**Workaround:**

- The only solution to recover from the freeze is to kill the `kwin_wayland` process.
