Microsoft's latest weekly update for the Microsoft Edge Dev channel is now available. This week, Microsoft is mostly focused on bug fixes as it looks to patch things up ahead of the next Beta channel release.

"You may notice that this is only one build away from last week's Dev, and that's because this is our candidate for our next Beta release, so we want to make sure it's extra polished before we release it there," Microsoft said in its post announcing the build. "However, that also means it's a pretty light week this week in terms of notable changes."

Here's a full look at what is fixed in this release:

  • Fixed an issue where typing in the address bar sometimes causes the browser to crash.
  • Fixed an issue where the browser sometimes crashes after completing the first run experience.
  • Fixed a hang during the first run experience.
  • Fixed an issue where the theme sometimes changes unexpectedly after the first run experience.
  • Fixed some issues with Application Guard windows not successfully opening.
  • Disabled hardware acceleration in Application Guard windows to prevent them from hanging on certain machines.
  • Fixed an issue where certain webpages don't open in Application Guard windows even though they should.
  • Fixed an issue where files that should be downloaded in Application Guard windows aren't.
  • Fixed an issue where an extra "Work" browser profile gets automatically created for some users (note that this may not remove the extra profile; a future fix will ensure that).
  • Fixed an issue where the Mac Touch Bar sometimes doesn't show the proper content.
  • Fixed an issue where the Settings page constantly shows "looking for updates" without ever completing.
  • Fixed an issue where certain settings are changeable even when they're disabled.
  • Fixed an issue where certain settings that are supposed to be enabled by default are disabled after performing a settings reset.
  • Fixed an issue where the Delete button does not appear next to downloads that have been blocked by SmartScreen.
  • Fixed an issue where the warning not to close the browser because a download is in progress appears even though the user isn't downloading anything.
  • Fixed an issue where websites that are blocked by SmartScreen aren't removed from history.
  • Improved scrolling behavior on the new tab page.
  • Fixed some issues with the PDF toolbar's hiding behavior.
  • Fixed an issue where switching between IE mode tabs and non-IE mode tabs leaves webpages at the wrong zoom level on certain devices.
  • Fixed an issue where no sites open in IE mode tabs when a certain combination of IE mode policies is applied.
  • Fixed an issue where tooltips in Collections all say "collection content" instead of the actual content.
  • Fixed an issue where certain print preview content is hard to read in dark theme.

There is a known issue to be aware of in this build, which causes Edge to occasionally launch with a blank window. According to Microsoft, if you launch another window and don't see the issue, you shouldn't see it again. If other windows you open are also blank, however, then you have to disable Application Guard to get it working.

Another build is planned to be released later this week to address the issue, Microsoft says.
