Window border dimensions appear during mouse resize

[sporteka2]

Description

When resizing the mlterm window with the mouse, the window border dimensions appear directly on the window. These dimensions are not useful by default - they just show the current width/height of the window frame.

Users find them distracting during normal operation as they obscure content and serve no practical purpose.

Steps to reproduce

1. Open mlterm
2. Click and drag the window border with the mouse to resize
3. Observe that window dimensions appear during the resize

Expected behavior

Window should resize silently without showing dimension information

Possible solution

Add an option to disable/hide these dimensions during mouse resize, or make them optional/debug-only. This could be controlled by a command-line option like --hide-resize-dimensions or via configuration.

Additional context

These dimension displays could potentially be useful for debugging, but should not appear by default.

Thank you for the report.
The dimension tooltip/overlay shown when dragging the window border is drawn and managed entirely by your Window Manager (WM), not by mlterm.
mlterm only provides character grid size hints (WM_NORMAL_HINTS) so the WM can display the size in columns × rows. mlterm itself does not render any resize overlay and cannot control it via configuration options.
If you wish to disable this display, please configure your Window Manager's resize geometry settings.

Since these dimensions are drawn by the Window Manager (WM) using the WM_NORMAL_HINTS provided by the client, removing them entirely would break the grid-based snapping behavior in many WMs. Instead of removing the hints, it might be better to add a configuration option or command-line flag (e.g., --disable-wm-hints) to let users decide whether to provide these hints or not. This way, users can disable the distracting overlay at the cost of losing snap-to-grid behavior.
