Periodically after wake up from sleep with external monitor connected, all apps on it becomes unmanaged: they disappear from Window Switcher, moving action not working on them, bsp-layout becomes broken
I have a feeling there is some race happening at that moment, but could catch exact root cause now.
Most of the time it reproduces with such flow: fresh boot -> connecting monitor -> moving windows to it -> sleep -> wake-up
Unmanaged windows on wakeup on secondary screen

Can you suggest what kind of diag I can gather to simplify debuging of such cases? Besides runing console app running in bg?
There was a bug in v0.13.3 where the invalidation window didn't refresh correctly. It has been fixed in v0.13.4. Please try the new version. If you still have issues, reply and I’ll follow up.

Still happening, only single window from each screen (across all desktops on them) is visible in window switcher on wake up
But now if you manually select one (click on it), it becomes managed and aligns with layout

Consistently reproducing wIth only main screen as well
I've tried to improve stability. Please try version 0.13.6 to see if it resolves the issue. I'll continue to investigate since I can't reproduce the bug myself.

It's a bit better now, all apps present in app switcher
But layout is still unmanaged (all apps windows are floating) and requires Tangrid restart
Even thought opening new one places it correct place acording to layout, but it's not being snapped when moved
The stability of 0.13.7 has improved further. If you have any positive or negative feedback, please reply here and I’ll keep following up!

I'd say it's mostly gone, at least I haven't had to restart tangrid since last update
Great, then I’ll assume it’s been fixed for now and mark the post as resolved. If there are any issues later, feel free to @ me.
