JetBrains Toolbox got black after upgrade to 1.7.3593

I have JetBrains Toolbox installed on my MacBook Pro(2015), it got black after upgraded.

Now the version is:

JetBrains Toolbox 1.7.3593 (Feb 14 2018)
OS kernel darwin 17.4.0 on x86_64

Here are three pics to show it.

1. Everything is OK.

2. Click any button like "Try", "Install" or options icon

3. Move cursor out

The whole GUI keep black, move cursor or roll page could change some elements to white or black.

Restart toolbox, I can repeat these 3 steps.
