I see the bug with kernel versions 4.19.17 and 4.19.13. I don't see the bug with versions 4.18.19 and 4.19.10. It seems some incompatibility between Emacs and Linux was introduced in one of the kernels 4.19.1[123]. I don't know how to debug this any further. > Alex -- Alan Mackenzie (Nuremberg, Germany).
