Empty login screen in VS2019

[ianleeder]

Just setting up a new dev environment, installed VS Community 2019 (v16.2.5), installed ReSharper (Ultimate 2019.2.2), installed GitHub extension (2.9.1.7781) and Bitbucket extension (1.41.2).

I have seen the exception stacktrace as per issue #97. I didn't do anything specific to fix it, next time I rebooted I could see the Bitbucket extension and login link as expected. However after clicking Login I'm presented with a blank window: If I move the mouse cursor around, it changes to indicate that the input fields actually are there, I just can't see them.

Issue still persists after restart VS or reboot.

I checked log file in %appdata%\GitClientVSExtension\Logs, this is the contents:

same issue on me. after clearing ComponentModelCache, no exception, but empty login. Reinstalling the extension seems to fix it.

I have also experienced this. What worked for me was:

1. Disable extension - Reset VS
2. Enable extension - Reset VS

I was trying to leave this in a broken state in case I could assist with debugging, but since it's gone a month without response I've given up. I tried Disable/Reset/Enable/Reset, but it didn't work for me. I had to uninstall then reinstall to get it working properly.

Mahapps causes a lot of issues in this plugin. I'm afraid I'll not be able to help with this, I must have stopped development of this project, hower I'm happy to approve any PRs with fixes.

It seems to me like this could be a rendering problem. Actually updating the Nvidia graphics drivers solved the problem for me.
