Display Issues

Hi,
I'm not sure if this is hardware related but I'm getting screen tearing and a flickering crosshair when panning 2d wireframe model space. Using Windows 11 with nvidia drivers. This doesn't happen with AutoCAD and is smooth, so I assume its a setting in Bricscad. Could it be the GLSWAP, currently on default 2 setting.

Thanks.

    I am on Mac but I also saw your post from 2019.

    I have similar Problems in V23 now when using GLSWAP "2" mode.
    (Which AFAIK was better in previous versions)
    I do not notice differences in 3D Views.
    It is only in 2DWireframe visual mode !

    E.g. rubber lines to cursor will dynamically refresh but forget to
    delete the old ones.
    And even GUI highlighting fails, e.g. you can't tell if Face or Boundary
    Selection mode I con is active or not ....

    I am not sure if "default" GLSWAP mode was always "0" before too.
    But when set to "0" the problems disappear.

    The flickering cursor happened when geometry (2d wireframe) had been selected and the grips are shown, in V22 the cursor would flicker. I did manage to solve this by turning of the grip attraction setting. V23 has solved this issue and I can now keep the grip attraction on.

    Turns out the screen tearing issue was my 4k monitor had a multi screen display setting turned on, once disabled it was fine. probably something to do with the refresh rate.

    I will try GLSWAP 0 because 2d wireframe has the same glitches you have mentioned.

    Thanks Michael !
