Amethyst causing OS crash on latest version

[danpalmer]

Describe the bug I believe Amethyst's most recent version is causing an OS crash. Not quite sure if it's a "kernel panic", but has the same effect. I believe it's Amethyst as a) it's the only app I have that I know messes about with windowing, b) it's an always-running utility, and c) I know it's recently had an update.

When opening my laptop having been away for some time, say overnight, I find the laptop is no longer on, and boots up. On startup I get a message from the OS saying my computer was rebooted because of a problem. This problem appears to be that the WindowServer crashed and/or did not respond to a sort of ping from the OS for a period of time.

A suspicious crash report in Console shows the WindowServer crashing at around the time I closed my laptop for the evening.

I've now experienced this crash 3 times in the last 4-5 days. It doesn't seem to happen every time, but regularly.

Applications: It appears to be an interaction with the WindowServer.

To Reproduce Steps to reproduce the behavior:

Nothing concrete, but leaving Amethyst running while closing a laptop and coming back to it some time later.

Expected behavior Amethyst should not hard-crash the OS.

Yeah, I've been getting similar crashes since using Amethyst as well. I've attached a crash report.

I think this may be correlated with some laggy behavior in Amethyst. Sometimes, my Amethyst commands can take multiple seconds (occasionally >10s) to actually execute, during which the Mac menu bar is completely frozen (beach ball).

I am running the following programs on my mac (Catalina 10.15.4):

• Emacs 26.3
• Google Chrome
• Safari
• VSCode
• iTerm2
• Zoom
• Toggl
• Slack
• Preview
• Activity Monitor

This froze again this morning, with over >1min lag in responding to certain commands like window resizing. It seems to be related to Pulse Secure's VPN credential prompt (which triggers every ~24h to renew my work VPN connection), but the correlation isn't very consistent.

I did not have such freezes before starting to use Amethyst, when I was just using Pulse Secure.

I looked at Activity Monitor and neither Pulse nor Amethyst were responsive. Killing Amethyst did not unfreeze my system, but killing Pulse and re-starting both did.

My version of Amethyst is 0.15.3 (88). Here is my debug info:
