The shift of the new cursor does not occur at the same time as the cursor icon changes. How to represent: 1. Open chromium, go to google.com, locale bottom line; 2. Move cursor slightly in _place_, where it must change (eg. text, text field or link); 3. Look closely: see one frame as the cursor icon is jumping; 4. Move cursor from this _place_ to blank; 5. Its jumping again Works in Konsole, Kate and anywhere else... Its annoying
The plasmashell does not position the cursor, especially not in Chromium windows. It could be a video driver or X11 server bug. I suggest to record a video of the issue and file a bug at https://bugs.freedesktop.org/
