Currently, I have identified several issues or missing functionalities:

1. Under Linux (Ubuntu 24.04, x11), IDE routines cannot move windows, and the window does not refresh when the program is first opened (no problem under Windows 11).
2. In the gallery routine, after adding multiple rows to the datatable, the data behind the scrolling datatable does not display.
3. Textfield requires selecting and copying/pasting text.
4. When the system displays that the zoom is not 100%, the position pointed by the mouse does not follow the zoom change, resulting in the incorrect position pointed by the mouse.
5. Unless otherwise specified, the above issues were tested under windwos11 25H2 26200.8457

Thanks for the detailed report @ands11! Let me break down each issue:

1. Linux (X11) window move + refresh:
Confirmed — the HitTestCallback is implemented on X11 but never actually invoked during event handling. This is a bug in the gogpu platform layer. Created gogpu/gogpu#270 to track this.

2. DataTable scroll after adding rows:
This looks like a virtual content height caching issue — when rows are dynamically added, the ScrollView may not recalculate the scrollable area correctly. We'll investigate and fix in ui.

3. TextField copy/paste:
This is tracked in #127. The selection UI (click-drag, double-click, Ctrl+C/X/V) is already implemented, but currently uses an internal clipboard instead of the OS clipboard. We're working on connecting it to the system clipboard via PlatformProvider.

4. DPI zoom mouse offset (Windows):
Confirmed — the wmMouseLeave handler dispatches raw physical pixel coordinates without applying DPI scaling. This is a bug in the gogpu platform layer. Created gogpu/gogpu#271 to track this.

Thank you for testing on both Windows and Linux — cross-platform reports are extremely valuable!

Several fixes have shipped since your report — lifecycle correctness (v0.1.46), unified draw queue (v0.1.45), and multiple dependency updates. Could you re-verify these issues on v0.1.47? Some may have been addressed.
