2023.3.20 - RDM Crash when RDP session Screensize is "Work size area"

avatar

Hi

Windows 11 x64 23H2 (Build 22631.2506)

RDM 2023.3.20

DVLS .2023.3.5

When opening RDP connections set to screen size "Work Area Screen" or changing a tabbed connection to "work size screen" win RDM freezes for 10 seconds and the close.

If I change settings or right-click and "Connect with Parameters" and select Tabbed og External the connection starts just fine.

Hi

Sounds good!

I can confirm that it is also present in .22 if you haven't tested yourself :)

Just curios, is this fix expected in next release .23+ ?

And are you gunning for a release of .23+ before the weekend starts?

Unfortunately, this hasn't been fixed in .24 either :(

Hello,

we are still investigating the crash, there's no ETA yet on the fix.

Hello

I've been able to reproduce the issue somewhat intermittently; given the symptoms that makes sense as it appears to be timing related.

Does the problem occur for you consistently, or only sometimes?

I'd like to ask a little more information:

  • In the "Display" tab, what do you have configured for "Screen sizing mode"?

  • In Options > Types > Sessions > Remote Desktop (RDP), in the "Advanced" section; is "Force reconnect when monitor is changed while using "work area" display mode" checked?

Thanks and kind regards,

Richard Markievicz

It is every time.

My settings:

I just tried disabling Force reconnect.... but still happens.

Hello

Thanks for the information. As a follow up question; last week I managed to reproduce once or twice connecting to a Windows Server 2k16 system. Today I've been trying with a Windows Server 2k22 server but haven't seen the issue once.

What server version(s) of Windows are you connecting to?

Thanks and kind regards,

Richard Markievicz

Yes, it seams that only Windows 11 and Server 2022 seams to have the issue.

and I mainly connect to 2022 :D

Just a random thought, could it be something with newer RDP uses both TCP and UDP? or is that part entirely mstsc.exe?

Hello

I do believe I found the issue here: it's very timing dependent so by that nature, some users would see this problem every time, some would see it intermittently and most would never see it all. I was only able to reliably recreate the issue by running a concurrent fuzzing tool to randomize thread scheduling.

I'm afraid the fix did not make it in time for today's 2023.3.25 release but should be in the next update. After you upgrade to the next version, please do post back if you still experience issues. I will try to update this post once the next version is available.

I apologize for the inconvenience.

Kind regards,

Hi

I'm just happy there hopefully will be a fixeven if that means waiting a few more days.

I will for sure report back when I have tested .25

Think I might have misunderstood you, but I have just upgraded to .25, and as you said, the issue still persists.

But I will report back again when next release is out :)

Hello

Yes, apologies for any confusion - my fix didn't make it in time for the .25 release but will be in the next version.

Thanks for your patience.
