21219 2008-09-29 13:13:15 -0700 Scrollbars don't render correctly with -webkit-transform 2008-09-29 13:33:27 -0700 1 1 1 Unclassified WebKit New Bugs 528+ (Nightly build) All All RESOLVED INVALID P2 Normal --- 1 brettw webkit-unassigned hyatt mitz oldest_to_newest 93268 0 brettw 2008-09-29 13:13:15 -0700 Scrollbars in absolutely positioned divs that have a webkit-transform applied don't render. I tested in Safari trunk. The transform doesn't even need to do anything (i.e. scale(1, 1) has this effect). I see in the scrollbar painting code in the Chromium port (I think Safari is identical here) that the origin of the graphics context is the upper left of the div, but the scrollbar positions are relative to the entire page. This means they're drawn outside of the div (and clipped away). The coordinates passed for the scrollbar position should be relative to the containing div so transforms such as rotation will be applied correctly. 93269 1 23918 brettw 2008-09-29 13:14:09 -0700 Created attachment 23918 Test case: absolute div with scroll overflow and scale(1, 1) 93271 2 mitz 2008-09-29 13:25:53 -0700 I cannot reproduce the bug in TOT WebKit on Mac OS X 10.5.5. The scrollbar does not hit-test properly, but paints correctly. 93275 3 brettw 2008-09-29 13:33:27 -0700 Testing error. I thought I was testing my own build from last week which was debug, but it was running my release version which is probably a month old. My r36857 is OK. 23918 2008-09-29 13:14:09 -0700 2008-09-29 13:14:09 -0700 Test case: absolute div with scroll overflow and scale(1, 1) absolute_scroll.html text/html 1178 brettw PHN0eWxlIHR5cGU9InRleHQvY3NzIj4NCiAgLmFzZGZza2V3IHtiYWNrZ3JvdW5kLWNvbG9yOiNF RkU7IGJvcmRlcjoxcHggc29saWQgYmxhY2s7IHBvc2l0aW9uOmFic29sdXRlOyB0b3A6MjAwcHg7 IGxlZnQ6MTAwcHg7IHdpZHRoOjIwMHB4OyBoZWlnaHQ6MTAwcHg7IG92ZXJmbG93OnNjcm9sbDt9 DQogIC5hc2Rmc2NhbGUge2JhY2tncm91bmQtY29sb3I6I0VGRTsgYm9yZGVyOjFweCBzb2xpZCBi bGFjazsgcG9zaXRpb246YWJzb2x1dGU7IHRvcDoyMDBweDsgbGVmdDo0MDBweDsgd2lkdGg6MjAw cHg7fQ0KICAuYXNkZnNjYWxlOmhvdmVyIHstd2Via2l0LXRyYW5zZm9ybTpzY2FsZSgxLjYsIDAu OSk7IH0NCiAgLmFzZGZza2V3IHstd2Via2l0LXRyYW5zZm9ybTovKnNrZXcoMGRlZywgMjBkZWcp Ki8gc2NhbGUoMSwgMS4wKTt9DQo8L3N0eWxlPg0KDQo8ZGl2IHN0eWxlPSItd2Via2l0LXRyYW5z Zm9ybTpzY2FsZSgxLDEpOyBwb3NpdGlvbjphYnNvbHV0ZTsgdG9wOjEwMHB4OyBsZWZ0OjEwMHB4 OyB3aWR0aDoyMDBweDsgaGVpZ2h0OjIwMHB4OyBib3JkZXI6MXB4IHNvbGlkIGJsYWNrOyBiYWNr Z3JvdW5kLWNvbG9yOiNFRUY7IG92ZXJmbG93OnNjcm9sbDsiPkZvdXIgc2NvcmUgYW5kIHNldmVu IHllYXJzIGFnbyBvdXIgZmF0aGVycyBicm91Z2h0IGZvcnRoDQpvbiB0aGlzIGNvbnRpbmVudCwg YSBuZXcgbmF0aW9uLCBjb25jZWl2ZWQgaW4gTGliZXJ0eSwgYW5kIGRlZGljYXRlZCB0byB0aGUN CnByb3Bvc2l0aW9uIHRoYXQgYWxsIG1lbiBhcmUgY3JlYXRlZCBlcXVhbC4gTm93IHdlIGFyZSBl bmdhZ2VkIGluIGEgZ3JlYXQgY2l2aWwNCndhciwgdGVzdGluZyB3aGV0aGVyIHRoYXQgbmF0aW9u LCBvciBhbnkgbmF0aW9uIHNvIGNvbmNlaXZlZCBhbmQgc28gZGVkaWNhdGVkLA0KY2FuIGxvbmcg ZW5kdXJlLiBXZSBhcmUgbWV0IG9uIGEgZ3JlYXQgYmF0dGxlLWZpZWxkIG9mIHRoYXQgd2FyLiBX ZSBoYXZlIGNvbWUNCnRvIGRlZGljYXRlIGEgcG9ydGlvbiBvZiB0aGF0IGZpZWxkLCBhcyBhIGZp bmFsIHJlc3RpbmcgcGxhY2UgZm9yIHRob3NlIHdobw0KaGVyZSBnYXZlIHRoZWlyIGxpdmVzIHRo YXQgdGhhdCBuYXRpb24gbWlnaHQgbGl2ZS4gSXQgaXMgYWx0b2dldGhlciBmaXR0aW5nIGFuZA0K cHJvcGVyIHRoYXQgd2Ugc2hvdWxkIGRvIHRoaXMuPC9kaXY+DQo=
