调研方向
Start by reproducing the issue in Eclipse SWT on Windows using the documented steps, comparing a runtime change from 100% to 150% with starting directly at 150%. Investigate the popup/context-menu icon handling during the runtime zoom-change path, using the toolbar and 175% cases as controls. Done means popup menu icons remain sharp after changing the display scale without restarting Eclipse.

描述
Summary: Popup menu icons are blurry when display zoom is changed at
runtime from 100% to 150%
Description:
Steps to Reproduce:
- Start Eclipse with the Windows display zoom set to 100%.
- Right-click any view (e.g., Project Explorer) to open a popup/context
menu. The menu item icons are sharp at this step. - Change the display zoom to 150%
(Windows Settings -> System -> Display -> Scale: 150%). - Do NOT restart Eclipse; right-click the same view again to open the
popup menu. - Observe that the menu item icons are now blurry.
Expected Behavior:
Popup menu icons remain sharp after a runtime zoom change, with the same
quality as when Eclipse is started directly at that zoom level.
Actual Behavior:
Icons in popup menus are blurry / pixelated after changing the zoom from
100% to 150% at runtime. Toolbar icons and other UI elements remain sharp.
Control tests (all performed on the same machine):
- 100% -> 175% at runtime: NOT blurry.
- Started Eclipse directly at 150%: NOT blurry.
- Started at 100% then changed to 150% at runtime: BLURRY (only this
combination triggers the issue).
=> The blur is specific to the runtime zoom-change path, not to the 150%
zoom level itself.
