The Intel community moderator has provided an update to the situation, they have released a Beta driver for Intel Graphics with the supposed fix for DWM leaking: Re: BUG: dwm.exe uses memory leakage with Intel HD Graphics 630 - Page 27 - Intel Communities
I am currently using that particular beta driver, and will be monitoring the DWM in the next 24-48 hours. The driver version in question is 30.0.101.1121.
