Suddenly text becomes hidden in Document editor

[HectorB-2020]

This issue is unique.

• [X] I have used the search tool and did not find an issue describing my bug.

Operating System

Windows 10 / 8.1 / 7

Version information

7.5.0.127

Expected Behavior

The content is preserved visible unless user intentionally drops or changes it.

Actual Behavior

Reproduction Steps

That was observed on Windows 10. Sadly I cannot surmise and hence report what exactly happened. But having assumed that that was a rendering issue, I tried maximizing and minimizing the editor's window, changing font colour, highlight colour, undo things. No way, all in vain. Thankfully copying the content was still possible. So I opened new editor windows and Ctrl-V pasted my text from the rotten window.

@HectorB-2020 Hi Does this problem reoccur or is it a one-time problem? If every time, can you send the broken file? If you can’t send the file, then perhaps you remember a scenario in which this can be done.

@XDmitryK, I certainly shall keep looking into this. So far the scenario is described above, I cannot add anything else.

@HectorB-2020 Hi I believe that the problem has not recurred for you, if so then we will close this issue.
