Dear Sirs!

I built WebKit2Gtk release 14.2 under Linux Mint 18 gcc compiler on

It works stable!

I use the product for embed web C++ application (Gtk-3).

I noticed some problems and I have some wishes with the product.

1. Size of downloading resource.

It is important for user to know the size of downloading resource. I know
that servers sometimes do not send this information. But sometimes other
browsers and curl can receive the size of resource, when WebKit2Gtk returns
0. I use curl in this case internally.

I wrote embed WebBrowser under MS Windows. IE WebBrowser Control always
knows the size of resource. Sometimes initially IE WebBrowser Control
returns 0, but when downloading starts, the IDownloadManager always know
total size of resource.

2. Scroll bars rendering often is strange. Scroll bars change own images.
Some old parts of page under transparent scroll bars are on them. Scroll
bars need to be invalidated?

3. Segmentation error when I was trying to read:

bool value = webkit_settings_get_allow_universal_access_from_file_urls(se

4. Compilation of an extension was problem. I defined symbol
__WEBKIT2_H_INSIDE__. After that I can compile an extension with WebView
and manually included <webkit2/WebKitWebView.h>,
<webkit2/WebKitNavigationPolicyDecision.h> and others.

5. I was trying to use model: WEBKIT_PROCESS_MODEL_MULTIPLE_

But second web page in the next notebook page do not start downloading. So
I was unsuccessful with the model.

6. User agent string. Well known in Russia mass media site
http://www.rbc.ru/ detected my browser as very old and there were serious
problem with rendering the site. When I change UAS to "Mozilla/5.0 (X11;
Linux) AppleWebKit/602.1 (KHTML, like Gecko) Chrome/54.0.2840.59 Safari/8"
problem disappeared.

But Google maps begun inform me with new UAS that «It is simplified mode.
Your browser do not support full version of Google maps». I consider that
Google maps rendering with Google Chrome is better that with WebKit2Gtk. So
Google maps is a good test from my point of view.

7. Font size for Web Inspector is too small for me. Some editable style
config for Inspector, including zoom control

will be good.

All I wrote may be not very serious remarks.

Thank you for the product!

I'll be wait new releases of WebKit2Gtk with inpatianci.

Best regards,

Oleg Milovidov.
