Desktop: App is starting into white screen after system booting up on Windows


Noticed after upgrading to 4.3.0 the app is just showing a white screen after a system reboot on windows.

There's no UI elements apart from the "Files, Edit, ..." menu at the top. so I take it the webview is not initializing correctly.

Opening up the developer console either through the menu or shortcut fixes it.

QA Test Steps

In windows, configure auto-start at login for the MM Desktop App. Log out and in again or restart your computer. MM Desktop App should auto start and the should not show a blank white window.

This appears to be working as expected now but the ticket is still in submitted status. Are you okay with me closing it out?

Tested on 4.3.2-rc1
This appears resolved for me on Windows 10.

I have this problem too on version 4.3.0.
Except this was not after upgrading, this was my very first time installation from scratch, responding to the demand of a specific organization.
On each computer start I have this blank window, and if I want to log in a specific server, I have to go to “Settings…” and click on the server name. Each time.
I don’t think this is normal.

On Windows 10 I can repro this consistently when auto-launch on system startup is set.
