Version: 4.4.0 (using KDE 4.4.5) OS: Linux Trying to load a specially crafted webpage with many :before and many :after involving css declarations of type display: table-* is impossible: the Konqueror application just hangs (CPU activity is maximized and remain maximized). Reproducible: Always Steps to Reproduce: Go to http://the-dees.webs.com/iepp1/02-gc-table-types.html Actual Results: - Konqueror 4.4.5 is unable to load the webpage - Matthew Dawson's plasmoid load system viewer 0.6 will clearly indicate a huge increase of CPU activity Expected Results: Webpage should load. - Firefox 3.6.8, Opera 10.60 and Chrome 5.0.375.125 load the webpage without problems - If required, I could create a reduced testcase out of the original webpage
The following 2 testcases create a hang situation: in fact, Konqueror 4.4.5 refuses to load the pages of the 2 testcases and then the CPU %tage of activity increases dramatically and remain high, maintain high. http://www.gtalbot.org/BrowserBugsSection/css21testsuite/after-content-display-011.html http://www.gtalbot.org/BrowserBugsSection/css21testsuite/before-content-display-011.html Both testcases have been submitted already to the CSS 2.1 test suite (RC1 build 20100917): http://test.csswg.org/suites/css2.1/20100917/html4/after-content-display-011.htm http://test.csswg.org/suites/css2.1/20100917/html4/before-content-display-011.htm Relevant code involved in after-content-display-011.html: <style type="text/css"> div:after { content: "Filler text "; display: table-row; } </style> <p>Test passes if there are two lines of "Filler text" below.</p> <div>Filler text</div> regards, Gérard
http://test.csswg.org/suites/css2.1/20101210/html4/before-after-display-types-001.htm (RC4) and http://test.csswg.org/suites/css2.1/20101210/html4/before-after-table-parts-001.htm (RC4) will also create an infinite reflow loop causing CPU activity maintained steadily very high (and a hang bug: application becomes unstable, unresponsive, prone to crash). Konqueror 4.5.5, Qt 4.7.0, Linux 2.6.35-24-generic-pae, i686 (32bits) here.
I still got an unresponsive application after trying to load http://test.csswg.org/suites/css2.1/20110323/html4/after-content-display-011.htm Konqueror 4.6.2, Qt 4.7.2, Linux 2.6.38-8-generic-pae, i686 (32bits), (Kubuntu 11.04 Natty Natty Narwhal) here. Links to testcases must use .../20110323/... Eg. http://test.csswg.org/suites/css2.1/20100917/html4/before-content-display-011.htm now becomes http://test.csswg.org/suites/css2.1/20110323/html4/before-content-display-011.htm regards, Gérard
Konqueror 4.8.1 with KHTML rendering engine Component: khtml Setting severity to GRAVE CONFIRMING KDE Platform Version: 4.8.1 Konqueror version: 4.8.1 (with KHTML rendering engine) Qt Version: 4.8.0 Operating System: Linux 3.0.0-17-generic-pae i686 (32bits) Distribution: Kubuntu 11.10 here. regards, Gérard
Bug is still there in SC 4.8.4. Another observation: memory consumption slowly increases, something like 1MB every few seconds on my Core2Quad.
