Description Michael 2024-05-05 18:22:20 UTC

SUMMARY
Currently, Chromium-based browsers require running natively on Wayland to provide pinch-to-zoom and swipe gestures. Although still not enabled by default like in Mozilla Firefox, some users report that they've been running Chromium-based browsers successfully under GNOME Wayland. See an example here https://www.reddit.com/r/linux/comments/1cklr5b/want_pinch_to_zoom_swipe_gestures_in_brave_chrome

However, in my testing on latest Fedora 40 with Plasma 6.0.4, the browser freezes and eventually crashes on force-quitting whenever a click and dragging action is performed. It seems the browser window becomes unresponsive to mouse inputs, although it still responds to keyboard inputs. But when closing the window the browser eventually crashes.

STEPS TO REPRODUCE
1. Set #ozone-platform-hint flag to "Auto" or "Wayland" in chromium:///flags and restart the browser
2. Drag some webpage element around or drag a URL/bookmark into the bookmarks bar

OBSERVED RESULT
The browser is frozen to mouse inputs when a dragging action is performed.

EXPECTED RESULT
The browser should not freeze or crash when clicking and dragging.

Screen recording reproducing the issue

During the demonstration I opened a new tab with the keyboard shortcut CTRL+T to showcase how the mouse click is unresponsive.

Especially because the issue is reproducible when dragging something from within the app itself, this is likely an issue in the app. But there's also a small chance it could be an issue in KWin, so I'm moving it there for the KWin devs to investigate.

In fact this is Bug 482142, which was just fixed for Plasma 6.1
