Dear Maintainer,

* What led up to the situation?
When lunching `sqlitebrowser` the windows is not displayed as it should.

* What exactly did you do (or not do) that was effective (or ineffective)?
In a Mate terminal I run:
$ sqlitebrowser

* What was the outcome of this action?

No terminal output and the `sqlitebrowser` window properly displayed.

I can confirm this issue on an up-to-date Debian/testing+sid installation.

The issue was reported upstream as
<https://github.com/sqlitebrowser/sqlitebrowser/issues/3811> (and also
as <https://github.com/sqlitebrowser/sqlitebrowser/issues/4099>, but
that didn't receive much attention).

Apparently the problem is somehwat related to using the proprietary
nvidia drivers (which I do).

The solution suggested there was to set the `QT_FONT_DPI` and
`QT_SCALE_FACTOR` envvars, and lo and behold! for me this did the trick:

~~~
QT_FONT_DPI=96 sqlitebrowser
~~~

I have no idea about how to get the correct DPI value for a given system
(96 works good enough for me), nor whether setting this globally might
have a negative impact on other applications (I don't think so).
