Description Juraj 2017-09-16 20:03:06 UTC

In the editor, when code checker find an error it highlights the wrong line with red background but when the error / wrong line is fixed error is removed from 'Problems' view but the line is still highlighted in editor and in minimap.

I tested this with Python file now but i experienced this with C/C++ as well

How to reproduce:
- Open file. (i tried only file which belongs to project)
- Write some wrong code
- Wait until the code analyser / checker marks the line as wrong
- Fix the error
- The line is still highlighted as wrong even when the error is not there anymore.

Additional information:
This behaviour is triggered when there is warning and error.
I tested it with Python file. I wrote wrong code / created error in a place which also PEP8 checker should mark as wrong (warning). Then i fixed the error but the line was still marker as error even after the warning was also removed.

Hm interesting, this looks unrelated to python actually, but instead like a renderer (?) bug. Will need to investigate.
