    but, pushing out the latest on develop now
    oh, it's done
    lol
    v2.80.0-alpha.8
    let me write some tweets

    This is going to be the new face of SkiaSharp
    not yet in this release, but the assets are in and ready

    @mattleibow This alpha 8 is built using clang 9 or 10??
    Matthew Leibowitz
    @mattleibow_twitter
    Clang 9
    Dariusz Komosiński
    @MarchingCube
    Was there any perf difference between 9 and 10?
    Matthew Leibowitz
    @mattleibow_twitter
    Havent actually done any testing
    Dariusz Komosiński
    @MarchingCube
    Ah, I was just wondering
    Matthew Leibowitz
    @mattleibow_twitter
    let me push that PR build and you can try any tests
    ah, that is the old code
    let me first update
    Matthew Leibowitz
    @mattleibow_twitter
    @MarchingCube I am pushing a version that uses Clang 10 right now... v2.80.0-pr.1286.3
    Both for Win32 and Linux
    @Gillibald You were using clang 10? Did you notice anything?
    Matthew Leibowitz
    @mattleibow
    @Gillibald rather... not sure what happened to that link
    Benedikt Stebner
    @Gillibald
    Can't really tell if there was a difference. I don't expect anything to change much.

    @mattleibow does Skia(Sharp) support a form of dirty rect invalidation? I have a large canvas and on an update i don't want to redraw every element on it, just a region where the update happens. very much like the new icon btw ;-)
    Dalton Spillman
    @daltonks
    @kai_low0n_twitter The way I found is by clipping the canvas using a path or region: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/graphics/skiasharp/curves/clipping
    In my scenario for an SKCanvasView, clipping is quicker than a full canvas redraw most of the time. However, it can end up being slower if you have enough dirty rects that cover enough area (even if they don't cover the whole canvas).
    Perhaps SKGLView clipping is faster though.

    Hi folks, your thoughts and opinions are needed. I am trying to decide if splitting the largish SkiaSharp package is worth it: https://github.com/mono/SkiaSharp/issues/1073#issuecomment-629692839

    @DM1145
    II read the notes - just want to clarify that the final app file size is or isnt affected……?
    Matthew Leibowitz
    @mattleibow_twitter
    not at all, pure packaging semantics
    DM1145
    @DM1145
    Cant see the value if it’s just faster to download - the issues that can come up with added complexity arent worth the one-time convenience.
    Matthew Leibowitz
    @mattleibow_twitter
    yeah
    and this is really a one-time thing. like, the very first time ever.
    DM1145
    @DM1145
    I’ve worked with a lot of projects that added complexity for what seemed like a good idea at the time, but required radical refactoring or full rewrite in a couple of years because it just became too difficult to keep moving forward. Can’t see the convenience value - unless it affected app file size/download speeds.
    DM1145
    @DM1145
    Thats my 2 cents worth (or 2 of your local smallest currency coin)
    Dalton Spillman
    @daltonks
    Yeah, the download size doesn't matter that much to me at least

    Currently native assets are broken for. Net Framework builds when AnyCpu is used. If we could specify the assets explicitly there would be no issue. Also custom builds just require a package reference. Currently we have exclude native assets from the main package.
    Matthew Leibowitz
    @mattleibow_twitter
    Hi folks, not sure if it was someone here or on Twitter that said they didn't like the fact a dotnet publish put all the native runtimes in the output folder of the apps...
    For example a dotnet publish for a netcoreapp3.0 will put tizen and ios
    I was thinking if you had any opinions or actual use cases, then just drop a comment here: https://github.com/mono/mono/SkiaSharp#1301

    @mattleibow_twitter wrong link - correct link mono/SkiaSharp#1301

    Ah, thanks.
    Seems my slack-to-gitter bot is not getting it right again

    @mattleibow_twitter hi there! I can't find a way to cap the frame rate of a SkiaSharp SKGLView. Is this possible at all?
    We are adding more animations and would like to cap the frame rate to reduce the power consumption, especially for mobile this can be important.
    Matthew Leibowitz
    @mattleibow_twitter
    What platform is this? Android? iOS should be good because it uses the display link. Last I checked, android was free running :disappointed:
    Right now, once way is to use a timer.
    I need to have a look at how you are supposed to implement this.
    Tomasz Cielecki
    @Cheesebaron
    @pauldendulk what we do is to set the SKGLView to only redraw when dirty. And have a controller which invalidates the view while the "rendering" we are doing on it claims it is dirty or when it fires an event when it needs a redraw
    Paul den Dulk
    @pauldendulk
    @mattleibow @Cheesebaron We will use it for all platforms. We now have a solution where use a timer to invalidate the canvas. It works okay. Not sure how it affects the smoothness of the animation. A simpler solution would be to invalidate the canvas within the render loop while the animation lasts. In that case I would like to cap the frames per second. I was expecting something like that was present, but if it is not it is not a big issue for us.
    Paul den Dulk
    @pauldendulk
    I would be interested to know how this is implemented in game components. I could calculate the time left until the next frame should start and pause for that duration in the renderloop. Would that be a smart solution? How to pause? Use Thread.Sleep? What would be the best option performance wise?

    @mattleibow_twitter @mattleibow is there some nuget feed where I can get SkRuntimeEffect binaries?

    @mattleibow_twitter
    Coming really soon. Just getting CI finished. For some arb reason it failed, but a retry should do it
