bug: PVE 虚拟机控制台里调出键盘后，虚拟机画面缩得非常小 #1639
Description
Activity
Issue triage
Feasibility:needs-clarification ｜ Risk:medium
Information needed to reproduce:
- Does this occur with all graphical console backends (VNC/SPICE), or only one?
- Does the console canvas shrink on other Android versions/devices, or only Android 16?
- Is the console hosted in a Scaffold that resizes when the keyboard appears, and does disabling resizeToAvoidBottomInset or overlaying the keyboard avoid the issue?
Suggested labels(not applied automatically):bug, android, virtualization, console
补充信息：
- 只用过图形（VNC）控制台；App 里也只有 VNC 与文本两种控制台，没有 SPICE，文本控制台不受影响。
- 只有这一台设备（Android 16）。
- 独立的「远程桌面」功能里是否同样缩小：未测试（两者是同一个查看器组件）。
- 关于 Scaffold：代码上确认图形控制台是
Column(toolbar, Expanded(canvas), _imeField)，且 Scaffold 没有关闭resizeToAvoidBottomInset——键盘弹出即压缩画布高度，画面按 fit 缩放，于是整幅桌面变小。
Additional details:
- Graphical (VNC) console only; the app offers just VNC and text consoles, no SPICE, and the text console is unaffected.
- A single device (Android 16).
- Whether the standalone Remote desktop feature does the same: not tested (both use the same viewer widget).
- On the Scaffold: in code the graphical console is a
Column(toolbar, Expanded(canvas), _imeField)and the Scaffold does not turn offresizeToAvoidBottomInset— the keyboard shrinks the body, so the canvas shrinks with it and the frame is drawn fit-to-size, which makes the whole desktop tiny.

描述 Bug
PVE 虚拟机的图形控制台里，点工具栏的键盘按钮调出软键盘后，虚拟机画面被压缩得非常小，几乎没法用；收起键盘才恢复。
复现步骤
期望结果：调出键盘时画面大小不变（键盘覆盖在画面上，或画面保持原尺寸可滚动）。
实际结果：画面跟着键盘一起被压缩。
更多信息（可能原因）
查看器是
Column(toolbar, Expanded(canvas), _imeField)，点键盘即聚焦底部隐藏输入框；系统键盘弹出后Scaffold默认的resizeToAvoidBottomInset压缩可视高度，Expanded的画布随之缩小，而画面按 fit 缩放，于是整幅桌面被缩得很小。🇬🇧 English
Describe the bug
In a PVE guest's graphical console, tapping the keyboard button in the toolbar (which opens the system keyboard / IME) shrinks the guest's screen to a tiny size — barely usable until the keyboard is dismissed.
To reproduce
Expected: the picture keeps its size when the keyboard opens (the keyboard overlays it, or the canvas keeps its size and can be scrolled).
Actual: the picture is squeezed together with the keyboard.
Additional context (likely cause)
The viewer is a
Column(toolbar, Expanded(canvas), _imeField); the keyboard button focuses the hidden IME field at the bottom, the system keyboard opens, and theScaffold's defaultresizeToAvoidBottomInsetshrinks the body, so theExpandedcanvas shrinks with it — and the frame is drawn fit-to-size, so the whole desktop becomes tiny.
