ID 215884 - Shift+4, Shift+6 behave like Shift+Left and Shift+Right when hovering the mouse over the Viewer​ panel on Linux

Follow

Problem summary
Shift+4, Shift+6 behave like Shift+Left and Shift+Right when hovering the mouse over the Viewer​ panel. This means it skips the Viewer forwards or backwards rather than setting the Viewers B input to 4 or 6. This only happens on Linux.

Customer reported version
nuke.9.0v7

Customer reported platform
centos6

Steps to reproduce

1) Open the attached InputsTest.nk script

2) Move the mouse over the Viewer panel, and press Shift+1 or Shift+2. The Viewers B input is set to that numbered input.

3) Press Shift+4 or Shift+6​ with the mouse still over the Viewer panel, you will see the frame indicator skip along the timeline.

Reproduced by support
The issue occurs on:

Nuke 8.0v1 Linux CentOS 6.7​
Nuke 8.0v6 Linux CentOS 6.7​​
Nuke 9.0v1 Linux CentOS 6.7​
Nuke 9.0v8 Linux CentOS 6.7​​
Nuke 10.0v1 Linux CentOS 6.7​


This seems to be a Linux only issue as I tested it on Windows and Mac and they behaved correctly. 


Expected behaviour
When pressing Shift+4 or Shift+6​ with the mouse over the Viewer, for the B input to be set to input 4 or 6

Actual behaviour
When pressing Shift+4 or Shift+6​ with the mouse over the Viewer​, the frame indicator skips along the timeline.​ The same as pressing Shift+Left or Shift+Right.
