           Summary: Atom text editor flickering when toggling tabs
           Product: plasmashell
           Version: master
          Platform: Neon Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: neek.san...@outlook.com
                CC: bhus...@gmail.com, plasma-b...@kde.org

Atom flickers really badly when switching tabs of open files (specifically a
TypeScript file and a JavaScript file) with atom-typescript package installed
and a tsconfig.json file in the project folder.


Reproducible: Always

Steps to Reproduce:
1. Install Atom text editor
2. On terminal: apm install atom-typescript (this will install Typescript
package for Atom)
3. Launch Atom (it should automatically install a dependency for the package,
it's a linter)
4. Open a normal folder with following files: tsconfig.json and test.ts
5. Contents of tsconfig.json can be an empty json file, with just two curly
braces in it ( like {} )
6. For test.ts, visit ' https://www.typescriptlang.org/play/ ' and copy paste
the script shown on the left side of the page into test.ts.
7. After that hit CTRL + S, this will compile test.ts to test.js, in the same
directory.
8. Now make sure test.ts and test.js are open in Atom editor as two tabs.
9. Now switch between tabs couple of times, if I'm not the only one, you should
see white flickering in the bottom part of Atom (make sure Atom is maximised,
funny enough, this does not happen at all when atom is not maximised)

Actual Results:  
Atom flickers when fully maximised (or Atom window size is more than 60% on
either axis of the screen), while switching between two tabs, of a Typescript
file and a JavaScript file. With atom-typescript package installed and
functional.

Expected Results:  
Should not flicker when Atom window size is anything more than 60% on both axes
of the screen.

Computer: Lenovo Y50 UHD Touch screen 
Resolution: 3840 x 2160 @ 48hz
Drivers: Nothing modified after I installed Neon out-of-box, same results with
Kubuntu out-of-box and Fedora as well.
