Win11 24H2 update can crash XSI (and fix)

[Sven Constable]

Hello list,

 

yesterday Microsoft was forcing the installation of the 24H2 update on my workstation. One of the bugs in the update seems to be that it resizes the desktop resolution temporarily, if the monitor goes into sleep mode (or is turned off manually). Probably only if it’s connected via display port or HDMI.

It might not be happening in everyones case and may depend on other thing like chipset/ graphic card driver as well. Not sure about that.

 

Application windows get resized and repositioned inbetween the monitor states. If XSI is doing hefty stuff at the time (eg. caching simulations), it doesn’t like that at all and will crash to desktop. No error message, it just disappears and an application error is logged inside the event viewer.

 

This worked for me:

1. Open regedit.

2. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\.

3. Under every "00" node, there are two parameters to change: PrimSurfSize.cx and PrimSurfSize.cy.

4. Modify all the parameters decimal values to the preferred resolution (the screens resolution you’re using). Make sure to change every 00 nodes value (they have subfolders with the same name. I changed them as well).

You don't need to restart the computer. Just turn the monitor off/on and you will see if it works.

Hi, just stumbled upon your post looking for a solution. I installed the same Win 11 update yesterday, and now I only get script errors when I try to create any Primitive or even a Null, I tried running "Runonce.bat" and re-registering "scrrun.dll" but no luck so far.

May I ask if you ran into the same issue ?

And maybe there's someone who knows a solution ?

The 24H2 is also causing trouble with jscript, but I don’t know if thats the problem you have.

Not been able to create primitives sounds like something else.

 

Solution from https://www.si-community.com/viewtopic.php?t=7398 regarding the jscript errors.

 

Snippet:

... the issue was that the new (called "legacy") jscript scripting engine doesn't like uninitialized variables. It can be disabled this way:
1. Win+R (run) gpedit.msc
2. In the group "Computer Configuration > Administrative Templates > Windows Components > Internet Explorer" double click the setting "Replace JScript by loading JScript9Legacy in place of Jscript."

3. set it to DISABLED
4. restart PC

Hey thanks for the speedy reply, so I assume you don't have this issue after this update ?

But I'll check it out, the errors mention some jscript errors, so who knows.

Fingers crossed...

[Sven Constable]

No, I don’t have that problem. XSI is working fine here.

Just in case someone else runs into this problem; it seems I just fixed the issue by hiding the "objSelectEvent" Jscript in the Addons folder the error was referring to.

Maybe this is causing other issues in the long run, but so far everything seems to work again.
