Problem Description

I installed spyder in a freshly created conda environment several days ago and it used to work just fine. I wanted to use spyder after an Ubuntu update but I cant click on the menu bar entries. When I am clicking on File, Edit, Search ect. thebackground of the text turns blue, so it recognizes the click, but the menu does not show up. I have no idea how to troubleshoot this. I cant still run my python programs in console and hotkeys are working but I cant’ access menus and thus the usage is quite limited. Also right mouse click doens’t seem to work, or the menu is again not displayed.

What steps reproduce the problem?

1. open spyder 3.2.8-py36_0
2. click on menu

What is the expected output? What do you see instead?

menu should open

My co-worker had the same issue and fixed it by leaving full-screen mode with F11. Don’t know what exactly is wrong, but it worked.

F11 does not work for me but i have realized that the problem is only in the external monitor. Also i have moved hald of the spyder to built in monitor and half of the spyder to 2nd monitor, there is no problem in the built in half. And also in this position, there is a problem.

But when i change it to this problem solved.
