Version

Operating System

MacOS, Windows

Eclipse version

2026-03

Bug description

In EGit's commit viewer, diff page, the find overlay has a gray background instead of white.

To reproduce:

1. Go to the Git history view, select a commit, choose "Open in Commit Viewer" from the context menu.
2. In the commit viewer (opens in the editor area), select the "Diff" tab.
3. Type Cmd-F

Actual behavior

(Note the gray background)

Expected behavior

White background, as in normal text editors:

Relevant log output

Other information

This is not a regression. Also occurs with older Eclipse or EGit versions.

OS: Mac OS 13.7.7

Unclear what might cause this. Possibly some CSS issue? I initially thought it could be because it's a read-only editor, but in the "Effective POM" tab when editing a pom.xml, which is a similar read-only editor embedded in a MultiPageEditorPart, the background is correct.

Can't test right now on Windows; will check on Monday.
