Is the panel at the top screen edge?

Does the issue reproduce in a new clean user account on the same machine?

Yes. I tested it on a fresh user account to exclude configuration issues.

Thanks. What GPU are you using?

> Thanks. What GPU are you using?

OpenGL core profile renderer: AMD Radeon RX 580 Series (radeonsi, polaris10, LLVM 17.0.6, DRM 3.57, 6.10.0-rc4)
OpenGL core profile version: 4.6 (Core Profile) Mesa 24.1.2-arch1.1

Btw, switching to software rendering does not change the behavior. So I don't think this is a rendering issue.

overlap, so the additional +1 is required.
