Category: Graphics Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Christopher King (popnose) Assigned to: Miguel (migueljmol) Summary: Jerky cursor movement with 2 monitors Initial Comment: My computer has two monitors, giving an "extended desktop". With an empty Jmol window nearly maximized on one monitor, the mouse moves the cursor smoothly. But, if the Jmol window is positioned so that part of the window is on the second monitor, then the mouse movement is extremely jerky: when the mouse is moved across the window at a "normal" speed, the cursor position only updates 4 or 5 times. (If this can't be reproduced, then the problem may be related to my using a Microsoft 5-button Intellimouse optical mouse.) If the problem is with Java, then there is nothing to do. I think I perceive the problem with a Jmol applet in a web page (when the page spans monitors), but the applet window is small, making the detection of the jerky motion subjective. It is peculiar that an empty window would have trouble updating the screen. Perhaps exploring this will lead to a way to improve Jmol's performance (which is already in the wow! category). ---------------------------------------------------------------------- >Comment By: Bob Hanson (hansonr) Date: 2010-03-22 17:12 Message: please report on latest Jmol 11.9 and 11.8. I'll check the same way you report there, as well. But is this only of vague interest -- is there any reason to have the Jmol applet on two screens? ---------------------------------------------------------------------- Comment By: Christopher King (popnose) Date: 2009-11-14 14:16 Message: Regression range: Present in 11.6.0; absent in 11.4.6 ---------------------------------------------------------------------- Comment By: Christopher King (popnose) Date: 2009-11-14 13:08 Message: I was able to reproduce the behavior on a classroom computer with a computer projector as the second monitor. That computer had a lower resolution than my office monitor. Also, the classroom computer has a regular 3-button mouse, so the mouse is not the cause of the behavior. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=379133&aid=2897779&group_id=23629 |
