Intel® UHD Graphics 770 had memory leak

[vgwei]

hi, In October 2025, I used a Dell OptiPlex Tower 7020 (with an Intel® UHD Graphics 770 graphics card) to run a professional program (which had previously run without issues on my computer). Currently, after running the program for 12 hours, I notice an increase in memory usage. Through observation using poolmon, I found a memory leak in the graphics driver,The paging buffer pool of the task manager also continues to grow.Currently, I have been able to run the system stably for 3 days by disabling the graphics card device. From October 2025 to March 2026, I tried reinstalling Windows 10 and 11, and updating the graphics card driver multiple times, but each time, memory usage increased, and the program crashed after 3 days

Hello vgwei,

Thank you for posting your query on the Intel Community Forum.

To help us better understand your issue and provide you with the most effective solution, could you please share the following details:

1. Which professional program were you running when you encountered this issue?
2. Did you verify that the program meets the system requirements for your current setup?
3. Did you observe this behavior only with a specific graphics driver version? If so, please specify which version.
4. Have you tried rolling back the drivers to check if the issue persists with an earlier version?
5. Intel SSU log - Please generate and share your Intel System Support Utility log following this guide: https://www.intel.com/content/www/us/en/support/articles/000057926/memory-and-storage.html

Hello Tharun_Intel,

Thanks,

I have tried the graphics card driver versions 32.0.101.7076, 32.0.101.7080, 32.0.101.7082, and 32.0.101.7085, all of which exhibit memory leaks. Currently, by disabling the graphics card, professional programs are running normally.
1. Both Dell and HP workstations (including the 770) have this issue, and disabling the graphics card is a solution
2. The professional program utilizes GDI+ for drawing, and it allocates and frees memory.
3. The professional program should have been running on previous computers for at least 5 years without any issues

Hello vgwei,

I hope you are doing great.

Thank you for your patience.

I wanted to share that as of September 19, 2025, Intel will be moving 11th - 14th Gen Intel Processor Graphics and related Intel Atom®, Pentium®, and Celeron® processor graphics to a legacy software support model. Intel will provide software support for affected products on critical fixes and security vulnerabilities only. Software updates for these products will move to a quarterly release cadence with additional critical releases as needed.

Only critical fixes and security vulnerabilities will be addressed in quarterly driver releases going forward.

Would like to continue with the support? Please note that even if the issue is fixed by our developers, the fix will only come to Intel Ultra Core Series 1 or newer drivers and will not be included on the driver of your graphics card. 

Additionally, could you please confirm whether this behavios is seen in other tools eg: furmark ?

Thank you for your cooperation, and we look forward to assisting you further.

Hello Tharun

Thanks！

It's not convenient to use Furmark for testing at the moment, but I can confirm that both methods operate stably:
1. Disable the graphics card
2. Use pre-allocated memory, similar to: allocating byte[1024] and not freeing it for cyclic use

Hello vgwei,

I hope you are doing great.

Thank you for your response and confirming that your system functions stably under both test conditions:

• Disabling the graphics card functionality
• Implementing pre-allocated memory management (byte[1024] allocation with cyclic reuse)

Your testing results indicate that the system is operating as expected with the implemented solutions.

Next Steps: To ensure we've fully addressed your requirements, could you please confirm:

• Are there any additional concerns or questions regarding system performance?
• Do you require further assistance with any other aspects of your setup?
• Can we proceed to close this support thread?

If no further support is needed, we will close this support thread accordingly. Please don't hesitate to reach out if any new questions arise or if you need additional assistance in the future.

Thank you for your co-operation.
