Graphical Linux applications in WSL2 too small?
In Windows 11, the new Linux environment (WSL2) can now also run graphical programs. These are displayed in a separate window and can be used like normal Windows programs.
However, there are problems with devices that use a high resolution, such as my Microsoft Surface Pro 7.

If we now start the GUI application again, it will scale like our Windows applications.
