Cannot select multiple lines of text in Eclipse 2025-09 on macOS Tahoe 26.1

[marcoscmdev]

After updating to macOS Tahoe 26.1, text selection in Eclipse 2025-09 (Build 4.37.0.20250905-1455) stopped working properly.

• Mouse drag does not select multiple lines.
• Shift + Arrow keys do not expand selection.
• Works fine in other macOS apps (TextEdit, VS Code, etc.)
• Happens even with fresh workspace and no plugins.

Steps to reproduce:

1. Open any Java or text file.
2. Try to select multiple lines using the mouse or Shift + ↓.
3. No visible selection is made.

Expected behavior:
• Normal multi-line text selection with mouse and keyboard works as intended.

Actual behavior:
• Selection is restricted to a single line.
• Crashes occur intermittently with Java 1.8 and the Genuitec plugin.

Same here - however in my case it's still possible to select multiple lines of text, only the visual feedback isn't working.

The text selection is made, but there is some problem with showing the selected text (blue highlight).
To see that text is actually selected, drag across (or shift-up/down) several lines and then type something, the part that was invisibly selected is replaced.

After further testing, I’ve confirmed that text selection does occur, but the highlighting is not visually rendered. The selected region is actually active — typing or deleting after an invisible selection correctly replaces or removes all the intended lines.

Currently, I’m using block selection mode (Cmd + Opt + A) as a temporary workaround, since this mode still shows proper visual feedback when selecting text with the mouse.

Given that one of the recent UI changes in macOS Tahoe 26.1 introduced system-wide transparency and compositing effects for icons and interface layers, this could be affecting Eclipse’s rendering pipeline — possibly related to SWT’s use of Metal or Core Animation surfaces on macOS.

It seems the issue is not input-related but rather a UI rendering regression introduced by the latest macOS update.

Duplicate of #2621, and according to that issue a fix has been implemented and scheduled for the next release
