RESOLVED FIXED 109469
[GTK] MOUSE_CURSOR_SCALE is not implemented

Summary [GTK] MOUSE_CURSOR_SCALE is not implemented
Zan Dobersek
Reported 2013-02-11 12:13:06 PST
Despite the CSS image-set feature enabled, the following two tests still fail: fast/css/cursor-parsing-image-set.html fast/events/mouse-cursor-image-set.html The first fails with a text diff failure, the other times out. In both cases the tests try to load mouse cursor images through -webkit-image-set(url(path/to/image)). That doesn't work, though - the image files are not loaded. It works on Chromium, signaling possible differences in JS bindings or even the KURL backend (or something else, I don't have much to grasp on).

Is MOUSE_CURSOR_SCALE activated for your port? I think this test requires it.

The test no longer crashes nor times out, so I've added platform specific results, because it only the scale parts fail.

It seems MOUSE_CURSOR_SCALE is not enabled on the GTK+ port. The test fast/css/cursor-parsing-image-set.html is passing fine (even without this enabled) and the test fast/events/mouse-cursor-image-set.html seems to be passing but is not really passing as it should do, as it has a gtk platform specific result that lacks the scale= values I suggest doing the following: - Remove the gtk+ custom expectation for fast/events/mouse-cursor-image-set.html and mark it as failing and assign it to this bug. - Remove fast/css/cursor-parsing-image-set.html from the list of tests expected to fail. Another (maybe better) option is to try to enable MOUSE_CURSOR_SCALE and see if it fixes also the test fast/css/cursor-parsing-image-set.html. But I guess a screen with HiDPI will be needed to test this properly (I don't have that)

If there is some test that needs to run manually in a HiDPI screen, my laptop has one, so just let me know and I'll give it a try.

Comment on attachment 317223 [details] Patch Looks good. Let's land this and keep the bug open for checking the possibility of enabling MOUSE_CURSOR_SCALE.

I think the tests should work regardless of having an HiDPI screen or not, as the test infrastructure mocks this things (AFAIK). My suggestion was more to actually test this on real websites and see how the browser renders the cursor. I don't know about an URL to test this, maybe opening the test itself on the MiniBrowser can be a good start.

We can actually just enable MOUSE_CURSOR_SCALE, since gtk already takes into account the device scale factor when rendering cursors.
