           Summary: blinking black screen and crash - HeidiSQL 11, Wine
                    5.0, Ubuntu 20.04
           Product: Wine
           Version: 5.0.3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When I start HeidiSQL, my screen blinks to black a few times and then halts at
a black screen. After waiting a few minutes, my OS becomes usable again, but
almost all applications (even non-wine) are closed. This won't happen for
instance for `wine notepad`.

Using:

* HeidiSQL 11.0.0.5919 ( https://www.heidisql.com/ )
* Wine 5.0.3
* Ubuntu Unity 20.04.1 ( https://ubuntuunity.org/ )
* Laptop: Dell Precision 7550
* Graphics: NVIDIA TU117GLM [Quadro T2000 Mobile / Max-Q]
** Using nvidia-driver-460

What could this be?

NB When I set Wine to emulate a virtual desktop, the blinking isn't there and
HeidiSQL can start. But this isn't a workable solution for me.
