marco and Metacity occasionally crashing on window close

[rnclark]

There have been recent threads about window manager crashing. For example:
viewtopic.php?f=206&t=340409&p=1960272#p1960272

search.php?keywords=marco+crash&sid=307 ... c65de72066

One suggestion was to switch to Metacity. I've done that and still get crashes. I'm on an I9 system with 128 GBytes ram, and dual 4K monitors. AMD 5700xt card, 5.8 kernel, mint 20.1, MATE. I can go for several days, opening and closing many windows spread across 8 workspaces. Then suddenly a window manager crash. At first I thought it was larger windows, but there does not seem to be a pattern. Firefox and gimp window closings seem to trigger the crash more often.So once opened, I tend to leave them open.

Error message with dmesg -w:

previous threads gave a partial recovery enabling one to save work then reboot.

Working solution to fully recover:
On first crash since boot (marco crash):

Preferences -> Look and Feel -> Desktop Settings
select windows
Change to Metacity + Compositing

When meticity crashes, do above but:
select marco + compositing
let that take effect (functionality not full restored)
no focus follows mouse and number of workspaces drops to 4
so go back and
select Metacity + Compositing

and we are back with full functionality. So, while an annoying problem (hope it is fixed soon) at least there is a recovery back to full functionality without rebooting (at least in my experience).

Update:

I get a more consistent crashes when the program has multiple windows open. For example with gimp, I have the tools each as separate windows on my second monitor and only the image window on my main monitor. When I close gimp, a dozen or so windows are closed and the window manager crashes.

Marco crash. This time after 5 days uptime. mint 20.1, dual 4K monitors and closing a single small window.

I'm still having marco crashes too. Closing a Firefox window will do it every time. Have seen it once or twice with another program which may be using a common library with Firefox perhaps.

[cebderby]

I'm seeing exactly the same, randomly but repeatedly.

Looking at the issues/releases on https://github.com/mate-desktop/marco
it seems that marco version 1.24.1 should include a fix for this, the Mint repository has 1.24.0-...

I see at https://pkgs.org/download/marco that Ubuntu 20.10 may have 1.24.1 but that Ubuntu 20.04 (base for Mint 20) is on 1.24.0.

How do we get Mint to take up the newer version?
