File containing what i thought would be necessary
When touchscreen mode is enabled (System Settings → Workspace Behavior →
General Behavior), context menus with many items overflow off the top of the
screen. The menu does not flip direction or constrain itself to the visible
area. Disabling touchscreen mode resolves the issue immediately without any
other changes.
Steps to reproduce
Enable touchscreen mode in System Settings → Workspace Behavior → General
Behavior
Right-click a folder in Dolphin that has many context menu items
Observe the menu overflowing off the top of the screen
Expected behaviour
Context menus should flip direction or constrain themselves to remain fully
within screen bounds regardless of the number of items.
Actual behaviour
Menus with many items overflow off the top of the screen. The menu does not
flip or truncate to fit. This only occurs when touchscreen mode is enabled —
disabling it resolves the issue — suggesting that the increased item
padding/height added by touchscreen mode pushes menus that would otherwise fit
just over the screen edge, and KWin is not compensating for this.
Additional context
The issue is 100% reproducible by toggling touchscreen mode on/off
Tested with both default Breeze theme and Ant-Dark theme — issue persists
regardless of theme
Tested with multiple resolutions and scale factors (1920×1200 @ 140% scale,
3840×2400 @ 200% and 300% scale) — issue persists regardless
Display is a 4K 16:10 panel (Dell XPS 13 9310 built-in display, 3840×2400
native)
