The interesting test is https://ci.eclipse.org/platform/job/eclipse.platform.swt/job/PR-411/1/testReport/junit/org.eclipse.swt.tests.junit/Test_org_eclipse_swt_graphics_TextLayout/testGlyphMetricsHeightDoNotImpachHeightOfUnrelatedChar/

and as expected, this same test passes on RHEL 7 (see #412)

@mickaelistria if you do not plan to merge this please close or convert to draft

[mickaelistria]

I don't intend to merge now as it would fail similarly to #411 ; but this test is still interesting, particularly if anyone is interested in fixing the issue, as it's the current minimal reproducer.
