U3423WE, macOS DDPM 1.3.0.0029, huge memory leak
Hello, I want to report a major issue with the DDPM software on Mac (M2) and I couldn't find a better place.
I'm running MacOs Sonoma 14.3 and DDPM 1.3.0.0.29 (latest), the app works but it has a huge memory leak after longer time use and mostly after computer goes to sleep.
Use case: Start DDPM > put Mac to sleep for a few hours > Wake up Mac
Result: RAM usage is almost max, and read/write on the SSD is huge. The OS moves extremely slow and it's mostly unresponsive until DDPM is closed. Then all comes back to normal.
Please fix this issue, otherwise the app is useless and it's a pity for users that need it for the monitor KVM management. (U3423WE)
Thank you.

MacBook Pro M2 (macOS 14.3.1 Sonoma)
DDPM 1.3.0.0029
macOS DDPM 1.3.0.0029 is the only version currently available. The older versions of macOS DDPM have been pulled due to security reasons.
Team put MacBook Pro M2 to sleep then woke up. DDPM’s CPU and memory usage are kept as normal. The possible reason on memory or CPU loading as the ColorSync.useragent may occupy CPU is a known Apple issue. User can open Mac Activity Monitor, screen shot top CPU and memory processes, DDPM CPU and memory usage.
Below are the instruction pictures on how to get DDPM "logs" from the macOS. Once found, upload them to a share that I can send to the team =

Hey,
I have the same problem. I'll bookmark this page share the logs once I observe the memory leak. It takes around 1-2 days.

All should uninstall 1.3.0.0029, restart the system and then test the new version =

My workaround for the time being is to restart DDPM anytime my machine has been asleep to free up the memory. For example, my WindowServer memory usage had increased overnight to 7.76GB; restarting the app dropped it to 1.1GB.

I start my Mac in the morning and put it to sleep at night, but if DDPM is running in the background, the Mac is extremely slow when I wake it up the next morning.
I have checked the Activity Monitor and found that the CPU usage of kernel_task and especially the RAM usage of WindowServer were very high.
- kernel_task CPU usage
- WindowServer CPU usage
- WindowServer RAM usage
If I quit DDPM, it returns to normal.17%->67%
10%->43%
1.4GB->5.5GB
I'm using DDPM V1.3.0.0037, U3223QE, macOS Sonoma 14.5, and MacBook Pro (13-inch, M1, 2020) with 8GB RAM.
