So I know it isn’t linked to any plugins. The webView instances will still show up after restarting Photoshop without any plugins installed. To test to see if it was linked to any plugins, I removed all Plugins, both my own and other developers plugins. Hi Microsoft Edge Webview2 is not an Adobe product: Try Microsoft support for Webview2 or. I’m pretty sure my plugins are not doing anything to cause these, at least not intentionally.

There seems to be a direct correlation between how many instances of Microsoft Edge WebView 2 there are running and how slow the UXP batches run.ĭoing a google search it appears others are seeing this too, although not specifically related to UXP. The time there were 7 instances was when the batch was running at 18 seconds per image. I have seen anywhere from 1 - 7 of these at once. When it starts slowing down, there are always instances of Microsoft Edge WebView 2 running underneath Photoshop in the dropdown. I found that when the UXP batches are running fast, in Task Manager, Photoshop doesn’t have anything in the dropdown next to it. there is plenty of available RAM for Photoshop when this happens. This is not being driven by RAM or scratch disk usage. Other times it is as high as 18 seconds per image running the same exact batch on the same folder of images. At times the batch processing is <5 seconds per image.

I have been testing a batch processing UXP plugin that I have in development.
