Click once in the track just below the thumb. Note that only half of the thumb is drawn hot. This regressed some time before February 20, 2009 (that was the date I filed this for Chromium). 117760 1 pkasting 2009-04-16 11:31:28 -0700 I have a fix for this locally. 117762 2 29540 pkasting 2009-04-16 11:36:06 -0700 Created attachment 29540 patch v1 Because we don't draw a hovered state if there's a pressed part, we need to make sure we invalidate any hovered part when we reset the pressed part, so that it can begin drawing its hovered state correctly. (The "half the thumb is hot" effect from before was due to the way the track and thumb rects overlap, since we were invalidating a track piece.) 117968 3 pkasting 2009-04-17 13:42:35 -0700 Fixed in r42624. 29540 2009-04-16 11:36:06 -0700 2009-04-17 12:04:06 -0700 patch v1 patch text/plain 1913 pkasting SW5kZXg6IFdlYkNvcmUvQ2hhbmdlTG9nCj09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT0KLS0tIFdlYkNvcmUvQ2hhbmdlTG9n CShyZXZpc2lvbiA0MjU4MykKKysrIFdlYkNvcmUvQ2hhbmdlTG9nCSh3b3JraW5nIGNvcHkpCkBA IC0xLDMgKzEsMTUgQEAKKzIwMDktMDQtMTYgIFBldGVyIEthc3RpbmcgIDxwa2FzdGluZ0Bnb29n bGUuY29tPgorCisgICAgICAgIFJldmlld2VkIGJ5IE5PQk9EWSAoT09QUyEpLgorCisgICAgICAg IGh0dHBzOi8vYnVncy53ZWJraXQub3JnL3Nob3dfYnVnLmNnaT9pZD0yNTIzOAorICAgICAgICBJ bnZhbGlkYXRlIHRoZSBob3ZlcmVkIHNjcm9sbGJhciBwYXJ0IHdoZW4gcmVzZXR0aW5nIHRoZSBw cmVzc2VkIHBhcnQsCisgICAgICAgIHNpbmNlIG9uY2UgdGhlcmUgaXMgbm8gcHJlc3NlZCBwYXJ0 IHdlIGNhbiBkcmF3IGEgaG92ZXJlZCBzdGF0ZS4KKworICAgICAgICAqIHBsYXRmb3JtL1Njcm9s bGJhci5jcHA6CisgICAgICAgIChXZWJDb3JlOjpTY3JvbGxiYXI6OnNldEhvdmVyZWRQYXJ0KToK KyAgICAgICAgKFdlYkNvcmU6OlNjcm9sbGJhcjo6c2V0UHJlc3NlZFBhcnQpOgorCiAyMDA5LTA0 LTE2ICBKdXN0aW4gR2FyY2lhICA8anVzdGluLmdhcmNpYUBhcHBsZS5jb20+CiAKICAgICAgICAg UmV2aWV3ZWQgYnkgU2ltb24gRnJhc2VyLgpJbmRleDogV2ViQ29yZS9wbGF0Zm9ybS9TY3JvbGxi YXIuY3BwCj09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT0KLS0tIFdlYkNvcmUvcGxhdGZvcm0vU2Nyb2xsYmFyLmNwcAkocmV2 aXNpb24gNDI1ODMpCisrKyBXZWJDb3JlL3BsYXRmb3JtL1Njcm9sbGJhci5jcHAJKHdvcmtpbmcg Y29weSkKQEAgLTI4Nyw3ICsyODcsNyBAQCB2b2lkIFNjcm9sbGJhcjo6c2V0SG92ZXJlZFBhcnQo U2Nyb2xsYmFyCiAKICAgICBpZiAoKG1faG92ZXJlZFBhcnQgPT0gTm9QYXJ0IHx8IHBhcnQgPT0g Tm9QYXJ0KSAmJiB0aGVtZSgpLT5pbnZhbGlkYXRlT25Nb3VzZUVudGVyRXhpdCgpKQogICAgICAg ICBpbnZhbGlkYXRlKCk7ICAvLyBKdXN0IGludmFsaWRhdGUgdGhlIHdob2xlIHNjcm9sbGJhciwg c2luY2UgdGhlIGJ1dHRvbnMgYXQgZWl0aGVyIGVuZCBjaGFuZ2UgYW55d2F5LgotICAgIGVsc2Ug aWYgKG1fcHJlc3NlZFBhcnQgPT0gTm9QYXJ0KSB7CisgICAgZWxzZSBpZiAobV9wcmVzc2VkUGFy dCA9PSBOb1BhcnQpIHsgIC8vIFdoZW4gdGhlcmUncyBhIHByZXNzZWQgcGFydCwgd2UgZG9uJ3Qg ZHJhdyBhIGhvdmVyZWQgc3RhdGUsIHNvIHRoZXJlJ3Mgbm8gcmVhc29uIHRvIGludmFsaWRhdGUu CiAgICAgICAgIHRoZW1lKCktPmludmFsaWRhdGVQYXJ0KHRoaXMsIHBhcnQpOwogICAgICAgICB0 aGVtZSgpLT5pbnZhbGlkYXRlUGFydCh0aGlzLCBtX2hvdmVyZWRQYXJ0KTsKICAgICB9CkBAIC0z MDEsNiArMzAxLDggQEAgdm9pZCBTY3JvbGxiYXI6OnNldFByZXNzZWRQYXJ0KFNjcm9sbGJhcgog ICAgIG1fcHJlc3NlZFBhcnQgPSBwYXJ0OwogICAgIGlmIChtX3ByZXNzZWRQYXJ0ICE9IE5vUGFy dCkKICAgICAgICAgdGhlbWUoKS0+aW52YWxpZGF0ZVBhcnQodGhpcywgbV9wcmVzc2VkUGFydCk7 CisgICAgZWxzZSBpZiAobV9ob3ZlcmVkUGFydCAhPSBOb1BhcnQpICAvLyBXaGVuIHdlIG5vIGxv bmdlciBoYXZlIGEgcHJlc3NlZCBwYXJ0LCB3ZSBjYW4gc3RhcnQgZHJhd2luZyBhIGhvdmVyZWQg c3RhdGUgb24gdGhlIGhvdmVyZWQgcGFydC4KKyAgICAgICAgdGhlbWUoKS0+aW52YWxpZGF0ZVBh cnQodGhpcywgbV9ob3ZlcmVkUGFydCk7CiB9CiAKIGJvb2wgU2Nyb2xsYmFyOjptb3VzZU1vdmVk KGNvbnN0IFBsYXRmb3JtTW91c2VFdmVudCYgZXZ0KQo=
