GUI in SQ X under Linux has issues

When running SQ X there are various issues in UI:
- Pressing Enter key in databank doesn't move to the next strategy 
- Listing through strategies with arrow up and down in databank doesn't work in 
- Deleting strategy in databank by pressing Delete key doesn't work
- Scrolling with mouse wheel doesn't respct natural scroll settings and also scrolls extreme slowly (looks like each wheel movement is just 1 pixel)
- When trying to copy date in Start or End date in Data tab date disappears after pressing ctrl+c


All these issues are not present when running  ./sqcli -gui and then accessing GUI using web browser. However in web browser file dialog is very impractical to use.
