    Hi!
    I'm running VcXsrv on a surface book 2. The resolution is 3000x2000. When I start in multiwindow mode, all works well, but things are a bit slow. When I run inkscape it can take several seconds for the screen to refresh. Dragging left-right-up-down is also not so quick. I tried to play with various command line parameters for vxxsrv, but none really helped. I also set LIBGL_ALWAYS_INDIRECT=1, which didn't help.

    MobaXterm is much faster, but the displayed resolution is lower.
    MobaXterm reports:
    Screen 0: minimum 0 x 0, current 1714 x 1143, maximum 4096 x 4096
    VcXsrv reports:
    Screen 0: minimum 0 x 0, current 3000 x 2000, maximum 32767 x 32767

    VcXsrv also looks much crisper.
    So, I have two questions:
    1. Is there a way to make 3000x2000 work faster? Some command line parameter that make everything faster (and I'm just talking about 2D for now....) Maybe increase memory? Or even use the nvidia gtx 1050???
    2. Is there a way to lower the resolution? I tried to play with the options -dpi and -screen 0 1024x768@1, but that didn't really work well. Best would be to have a resolution of 1500x1000 - so integer scaling, but maybe faster.

    Thanks!
