This is the issue about bad performance experience ,so I locate the priority level to most one.

The issue is like that :
Hi folks

Recently I found when I try to use different type of fonts expecially "wqy-unicode" type, I found the efficiency is very bad when the screen need to update .

It might be the important bug which might impact on the wide application for this software.

You could use attachment file to open .

firstly the open operation should be very slow
further, when opened, you try to zoom in/out, the response is unbearable...
you could also open another file ,then switch to this opened file, the switch response is also very unbearable....

but my file just contains limited text symbol. I don't think this is the expected efficiency. other CAD software behavior well actually.

    I agree we should support native Qt fonts (non-stic fonts) in the next version.

    I downloaded this file and try to open it with the latest master branch, I don't really see performance issue on my laptop.

    I can open the wqy-unicode-very slow.dxf file smoothly, and zoom in/out smoothly, and switch to/from this file smoothly.

    I'm using Gentoo/Linux on i7-3720QM CPU with 8GB RAM.

    Now, I'm wondering there's another bug triggered at your side.

    I tried on another windows PC with latest version.
    the output is like below as expected.

    MY PC Configuration is :

    But The performance is still bad . I don't think If I upgrade to I7 CPU. the performance will be "Smooth". There must be something else difference on our side. Thanks.
