Might be related to eclipse-platform/eclipse.platform.ui#3884

I can reproduce this issue, but it only happens with dark theme. Light theme is fine for me. And you will also see results in dark theme once the result list received focus (by clicking into it or using Tab).

Looks like some UI updation glitch..

It seems like a bunch of appearance/behavior changed between macOS 15 and macOS 26 without Apple having that properly documented. I expect that people interested in keeping Eclipse/SWT working on macOS will have some work to do to adapt those changes. For the time being, we should just move back to compiling Equinox binaries on macOS 15 to have a usable state again (as proposed in eclipse-platform/eclipse.platform.ui#3884 (comment)), but that's just a temporary solution.

I am also seeing these issues in the dark theme on macOS.
