Awesomium.NET Crashing on Resize - Memory Leak

Question

Well I have noticed a weird bug.This occurs on resizing.

I First noticed it while I was trying to fix my xaml alignments. When I try to resize the window across my 2 screens the awesomium content was starting to flickering and suddenly content dissapeared and the redscreen with the logo came up, short after vshost32.exe crashed.

I thought well.. ok it might have some width limitations so I limited the MaxWidth of the window on Primary Screen's Width. I noticed some flickerings aswell while I was trying to resize it horizontally, but that was all, however when I spammed the resize and changed many times height and width the same issue occured on maxheight 1080 and max width 1920.

Edit2 Additional information: I have 2 WebControls on the same XAML. When i added multiple, and resized... it crashed the first second.

It seems to me that there's some meory leak here.

After 2 GBs of Wasted Ram, it gets crashed.

Tried it with 8.5 GB of Ram used, gone up to 10.5 and then crashed.

I've made some tests in order to find what is causing this error. I created a loop that it would resize the window at 2 widths and heights every 50 ms

 public async void testc() {
        for (int i = 0; i <= 1000; i++)
        {
            this.Width = 1700 + i % 2;
            this.Height = 950 + i % 2;

            await Task.Delay(50);
        }
    }

it crashed again as expected, interesting is though, that when i appended at the loop

WebControl.Reload(true);

it actually didn't crashed... Memory was going up and down from 350 MBs

Is there anyway to prevent Rendering while resizing?

Seems like a bug in Awesomium. I'd create a very minimal example that repro's the issue and submit it to their bug tracker. — Lynn Crumbling, Nov 25 '15 at 20:29
It seems like Awesomium has been abandoned for like a year now. — Devian, Nov 25 '15 at 21:07
The community at http://answers.awesomium.com/ seems like it is vibrant. I'd try posting there. Looks like an older version of the Stack Overflow engine. — Lynn Crumbling, Nov 25 '15 at 21:18

Cool. Good luck.. Hope someone has some insight for you. I wasn't aware that the product wasn't being maintained; you can still purchase licenses. — Lynn Crumbling, Nov 26 '15 at 01:56
This happens on CefSharp also. It's been 3 days I am trying to find a solution. — Sabri Meviş, Dec 24 '18 at 13:43

Think you can resize only after your control has fully initialized and displayed. IMHO bitmap

 at System.Windows.Media.Imaging.WriteableBitmap..ctor(Int32 pixelWidth, Int32 pixelHeight, Double dpiX, Double dpiY, PixelFormat pixelFormat, BitmapPalette palette)

is zero size or invalid.

I used Awesomium in the past, my suggestion is to migrate to CefSharp

To be honest i migrated to CefSharp 2 Days ago after the several issues i faced with Awesomium. And i'm pretty happy now. I thought cefsharp would be heavier but it seems to load just fine, and is way more optimized than this abandoned project. Thank you for your time anyway. – Devian Mar 10 '16 at 13:36
Interesting. This happens on cefsharp also while resizing on 4k screen. – Sabri Meviş Dec 24 '18 at 13:44
