Win11 24H2 update can crash XSI (solved)

Post by scon » 20 Jan 2025, 17:09

Hello,

If you ever wanted to crash Softimage by turning off the monitor, it has been finally made possible by microsoft. ;)

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.
