There seems to be a problem affecting the Doc Switcher dialog of Notepad++:
When running Notepad++ for a long period inside Wine, file names are displayed
at wrong positions or appear multiple, sometimes only half lines are displayed.

Resizing Notepad++ main windows sometimes temporary corrects the complete file
list, but not always.
Clicking at a file name at his list always leads to a correct redraw of this
one file name
(watch attached movie).

Only the Doc Switcher dialog is affected: all other Notepad++ sub windows seem
to be correctly redrawn.

Seen at any releases of SuSE and Ubuntu during the last years. Also at
different computer hardware.
Seems to affect any Notepad++ releases (current I use 8.1.2).
At MS Windows this problem does not occur.

Steps:
Enable "Document List Panel=Show" at Menu Settings/Preferences/General.
Open and close some text files over a long period .

Right after start of Notepad++ everything seems to be OK.
The redraw problem needs some time (hours?) to appear.
Possibly computers Stand-By mode also has an influence.
If the problem appears, it will not go away until Notepad++ is restarted.
