Memory leak when file is open

[robotbuilder25]

Hello,

When using a fresh install of UCCNC (version 1.2113) on a fresh install of Windows 10 or 11, opening any nc file causes the memory to continually grow until the computer runs out of memory and the program crashes. The memory only starts to continually grow once a file is open. Closing the file stops the memory from growing. If no file is open, the memory does not continually grow. The amount the memory grows per second appears related to the size of the file (the larger the file, the more the memory increased per second). It looks like the GPU memory also continually increases due to this. Once the system page file has been completely filled up, the program crashes.

I am using the default install of UCCNC version 1.2113 wit the default profile and no custom settings or anything. I just installed UCCNC, and then opened the program and loaded an nc file.

I've pasted the system information and crash from Event Viewer below. Looking at the crash stack, it looks like maybe a gpu memory buffer is not being freed correctly.

The datas are all freed properly otherwise other users would have the same issue.
The memory garbage collection is automatically handled by the .net framework though, so if this issue happens it is very likely to be a .net framework issue.
Try to reinstall the .net framework or install another version.
Version 1.2113 UCCNC requires the .net framework 4.x , so any 4. version of .net framework works, 4.0, 4.1, 4.2 etc.

Could you share the file to see is I have similar issue? My setup is close to yours

Seems like I am having the exact same issue, with .NET 4.8.04084 Full

Did you downgrade to something that worked?

Thanks,

ROBOTBUILDER25,

Did you find a solution to this? I have the exact same issue.

Thanks, John
