Hello again!
After some more detective work, I noticed that the issue did not occur on self-compiled WindowMaker from the git-repo, which made me think what the debian packaged version might be doing differently ...
It turns out that the deb passes "--enable-randr" flag to wmaker configure, which is the root cause of this issue. The option flag
is marked "enable RandR extension support (NOT recommended, buggy)". Doing a rebuild of the package with edited debian/rules that has --enable-randr removed fixes the problem. It seems that the flag was enabled in this change: https://anonscm.debian.org/git/pkg-wmaker/wmaker.git/commit/debian/rules?id=e737a261679e2db0ae80c8087302f88d8569859a -- ] ccr/TNSP ^ pWp :: ccr tnsp org :: http://tnsp.org/~ccr/ ] PGP key: 7BED 62DE 898D D1A4 FC4A F392 B705 E735 307B AAE3
