After upgrading our instance from Madrid to Orlando, we've observed that UI is distorted in service portal widgets . We've noticed this issue occurring in Microsoft Edge (non chromium version) but seems to work fine in Chrome.
Confirmed in Orlando
The issue is caused when in Microsoft Edge, Adobe Flash is turned on by default in which can cause issue in how Service Portal displays. It is recommended to turn off flash to not cause any conflicts on the page.
1. Go to the three dots in the Browser and go down to settings
2. Click Advanced and uncheck "Use Adobe Flash Player" to off
3. Refresh the page
