No, I still encounter massive lag spikes with dwm.exe after a few weeks of uptime, and restarting the process fixes it. However, I get lag in the Windows UI itself, not games. I think it has something to do with one of my monitors always disconnecting from the computer when it goes to sleep, so Windows acts like I'm constantly plugging and unplugging the monitor multiple times a day, for weeks. Leaks like 200-500MB+ each time, and dwm.exe is often using close to 3-4GB when I kill it.

few weeks of uptime? If you are not running any servers on windows, that shouldn't be an issue. Just shutdown your pc like a normal person.

Standby/Hibernate counts to your uptime. It's a "normal" feature "normal" people use.

I do run a few VMs and servers on it. Plus opening back up all my work after a restart is a pain.

That’s extremely odd, and you’re not on some older Windows 10 build or LTSC? I definitely have long uptime bugs on my work computer but they’re more to do with Explorer than DWM/UI.

W10 Pro for Workstations, kept up to date.

Never had any issue like this until I had to replace a monitor, and the newer one doesn’t keep HDMI/DP signals alive at all when the display sleeps, causing Windows to think it disconnects.

It’s such a stupid and common thing that the “PersistentWindows” tool exists to put the windows back in position after W10 fucks up everything from the monitor disconnect. So it’s not a stretch to think dwm.exe has issues with it as well.
