Changing displays causes intermittent hangs (crashes)

[Pun-e]

Version

2.2 A4

Operating system type + version

Win 10 64 Pro - Surface Pro

Behavior

I start the slicer, and everything is fine.

If I unplug my docking hub, sometimes (it used to be everytime, but it has improved recently), I'm presented with this:

This is PrusaSlicer scaled to my Surface's screen, failing to update to the new resolution of my external monitor.

I'm not sure what information you need from me to properly diagnose this issue, but just let me know. It's a very circumstantial bug but it always pops up when I'm least expecting it.

Do you have your surface display active in addition to your external display? Or is just the external display active when plugged into the docking station? čt 27. 2. 2020 v 7:41 odesílatel Pun-e <notifications@github.com> napsal:

Undocked = Surface in-built screen
Docked = 2 external HDMI monitors

I saw this bug, but the person who opened it just abandoned it. I'm thinking they're probably associated

Thanks, we have a windows laptop with a docking station with 2 display outputs available, we can test it. What is the model of your Surface? Is it a tablet style computer or a laptop? čt 27. 2. 2020 v 10:31 odesílatel Pun-e <notifications@github.com> napsal:

This model i7 + iris 540 graphics

The next time it happens, is there any log or something I can get that will offer some further details / insights?

[bubnikv]

We were able to reproduce the issue on one setup of one of our IT guys. We were not able to reproduce the issue on our development laptop. It will take some time to resolve the issue as we cannot reproduce on our development computers. čt 27. 2. 2020 v 14:23 odesílatel Pun-e <notifications@github.com> napsal:

It happened when our IT guy put his computer to sleep after running slicer on his laptop in standalone mode, and then he plugged his computer into his docking station and then he woke up the computer by the power on button on his docking station. Is this your scenario as well? čt 27. 2. 2020 v 15:04 odesílatel Vojtech Bubnik <vojtech.bubnik@prusa3d.cz> napsal:

I'm not too sure what "standalone mode" is, but yeah, going to sleep seems to make it more likely to happen. Although I can cause the issue to happen just by toggling power to my dock. When power is switched off, it counts as a disconnect. I literally just froze the slicer again testing that.

It also seems more likely to happen after I slice something.

Yeah, just tested that too. If I just open the program and don't slice anything it didn't freeze after 3 toggles, sliced a file and it froze on the next connection.

Process:

1. undock device
2. Open slicer
3. Insert this file [Github wouldn't let me attach as too big, 60MB+)
4. Slice
5. Connect dock

For me, this will freeze it every time. Sometimes I can use slicer for a few seconds before it freezes but I've successfully frozen it 4 times in a row now

We reproduced it on one laptop. When we tried to collect crash logs using

https://docs.microsoft.com/en-us/windows/win32/wer/collecting-user-mode-dumps

and to trigger the crash dump manually over the hanging process with

https://docs.microsoft.com/en-us/sysinternals/downloads/procdump

Create the process dump by executing the following command, or the one provided by a helper:

ProcDump.exe -ma <process name or PID (Process ID)>

we are no more able to reproduce the hang once we enabled crash dump collection for PrusaSlicer, so we are stuck. You may try to collect the crash dump for us if you manage.
