So, I did the windows part too (and make sure it really fixes the crash!) Done [74183ad460eb6ef6|here] erikleunissen added on 2026-03-26 08:04:31: I confirm that the crash doesn't occur anymore with branch bug-8c3620752c at commit [4f77fbcac5]. marc_culler (claiming to be Marc Culler) added on 2026-03-25 21:44:07: I pushed a fix for aqua as branch bug-8c3620752c. The fix just avoids using winPtr->parentPtr when it is a NULL pointer. I will leave the Windows case for someone who knows their way around the Windows code. marc_culler (claiming to be Marc Culler) added on 2026-03-25 19:57:31: That command is something which I had not heard about before. So I
looked at the manual.
The manual entry for wm forget says:
"wm forget window
The window will be unmapped from the screen and will no longer be managed
by wm."
The manual entry for wm withdraw says:
"wm withdraw window
Arranges for window to be withdrawn from the screen. This causes the
window to be unmapped and forgotten about by the window manager."
What is supposed to be the difference between those two things?
oehhar added on 2026-03-25 10:45:20: I remember that we had a patch to trap this, origin from Androwish. I may be wrong... Will look later, Harald | |||
