Glitches related to the screen closing due to inactivity

[Efthimios Chaskaris]

I can't replicate this issue. Its appearance seems random.

Steps taken:
1. Have the screen close due to inactivity.
2. Open the screen by e.g. moving the mouse.
3. The login screen "banner" appears. This time, however, the application bar (and maybe even the top status and notifications bar) can be seen.
4. Press enter to remove the banner and reveal the desktop environment.
5. The desktop environment is not revealed and there is the characteristic pink reddish background of gnome in place of the banner(1st glitch).
6. Put your PC to sleep through the pause button in the menu in the top status bar.
7. Reopen your PC.
8. Press enter to reveal the desktop environment.
9. The desktop environment is revealed and is functional for the most part. However, the application bar acts really weird. For example, if you put the mouse cursor to the edge of the screen, you can't click the Show apps button (2nd glitch).
10. Press alt-F2, r and then enter to restart Gnome. This fixes the previous issue.

I'm sorry, it's just that they appear at the same time and I can't reproduce them.

I'll take some pictures when the glitches appear again. It may take a few days for them to appear, though.

The first image is the first one you see right after the screen opens.

The second image is what you get after pressing enter. No text field for password input appears.

The third image is what you get after you have waken the PC from putting to sleep as described above to circumvent the issues. This time you can type the password.
