High system load due to weather widget

[klamann]

Hi, the weather widget frequently causes 100% load on a single CPU core and eats up several gigabytes of RAM until I kill the process.

The actual process that causes this is msedgewebview2.exe, but in the parameter list I found --user-data-dir=C:\Users\$user\AppData\Roaming\ExplorerPatcher\ep_weather_host\EBWebView, so I assume this belongs to the weather widget of ExplorerPatcher. Please note that this process will not terminate by itself, no matter how long I wait. Sometimes, more than one instance of msedgewebview2.exe will run, each of which will cause 100% load on a CPU core and eat up several gigabytes of RAM.

Obviously, this is a huge waste of resources. I deactivated the weather widget for now, but I would really like to use it again. It used to work just fine at some point (or maybe it didn't and I never noticed until now, not sure).

Here's the full command of one of the rogue processes

C:\Program Files (x86)\Microsoft\EdgeWebView\Application\117.0.2045.31\msedgewebview2.exe
--type=renderer
--noerrdialogs
--user-data-dir=C:\Users\$user\AppData\Roaming\ExplorerPatcher\ep_weather_host\EBWebView

 /pfhostedapp:039cfc2eab642feb6a5fcd8c7792da43c491ecfb
 /prefetch:1

and here's another instance

C:\Program Files (x86)\Microsoft\EdgeWebView\Application\117.0.2045.31\msedgewebview2.exe
--embedded-browser-webview=1
--webview-exe-name=DllHost.exe
--webview-exe-version=10.0.22621.1
--user-data-dir=C:\Users\$user\AppData\Roaming\ExplorerPatcher\ep_weather_host\EBWebView
--noerrdialogs
--embedded-browser-webview-dpi-awareness=2
--allow-insecure-localhost
--disable-site-isolation-trials
--disable-web-security
 --enable-features=MojoIpcz,msSingleSignOnOSForPrimaryAccountIsShared
 --lang=en-US
 --mojo-named-platform-channel-pipe=8312.8388.7450525086601872397
 /pfhostedapp:039cfc2eab642feb6a5fcd8c7792da43c491ecfb

both of these were running at the same time at 200% CPU load, ~4GB RAM in total, about 5 minutes after I woke up my PC from standby.

This problem has been there since at least June 2022. It only occurs when returning from S3 standby and even then maybe every other time. I haven't reproduced this on Modern Standby (S0) machine.

Does this happen if you uninstall EP and reboot? Then try going into stand by s0 mode and wake up from it?
