Category: editor core Group: None >Status: Closed Resolution: None Priority: 5 Private: No Submitted By: LHEZ Gael (myshforum) Assigned to: Nobody/Anonymous (nobody) Summary: Abnormal window redrawing/screen flutter with core2duo Initial Comment: Hi, I'm using jEdit 4.3pre7, but I noticed that bug with older version (in fact, I tried from 4.3pre3 to pre7). Before I was using older jdk (1.5_06) and I never such window redraw (I explain that below). Since the jdk1.5_08, and now the 1.5_09, Swing is redrawing the screen too much time. By window/screen redrawing, I mean that swing is redrawing the window entirely, and I see the redraw (eg: for a duration of 1/2s, I can see gray on the bottom of the window, etc.) If it were from time to time, it wouldn't be such a nuisance, but yet it's redrawing the window each time I'm selecting (for example) a directory in the project viewer, or when I'm just playing with the menu. If you don't understand, then wait a little : I go take a video of that (after all, it would be more explicit). I don't know if my video card is guilty (well, my MSI7900GTO 512Mb works fine in Titan Quest, so I don't see why it should fails with a swing apps?). I will try it on another PC - with a 6800GT, and jdk1.5_06 I think. Note that plugins are not in cause : this redraw window even with a fresh install of jEdit. ---------------------------------------------------------------------- >Comment By: LHEZ Gael (myshforum) Date: 2006-10-30 18:38 Message: Logged In: YES user_id=371121 As expected, taking a video don't show much my problem either with a DV cam or via a screen recorder : I have a redraw, but not my "bug". ---------------------------------------------------------------------- Comment By: LHEZ Gael (myshforum) Date: 2006-10-23 10:40 Message: Logged In: YES user_id=371121 I will test it in full detail with -Dsun.java2d.noddraw=true, but for what I've seen, it's still present when I open the main menu. I don't know if it would fail with linux (I'm on Windows XP SP2). Note that the video card driver are the same on both PC (nvidia display drivers 91.47). kpouer> yes, it happens often (every time I use jEdit, and its really annoying, reproducing it is simple : I just go into the menu, or simply use jEdit). I will continue the java2d thing, as it seems to resolve a little my problem (but it's still there, I will test it longer to check if it's better or not). And I will look into taking a video of my weird problem. Perhaps it is related to other apps (currently running KVirc, Thunderbird1.5, Fx2.0rc3, foobar2000, gaim and of course my beloved jEdit) ---------------------------------------------------------------------- Comment By: Matthieu Casanova (kpouer) Date: 2006-10-23 09:12 Message: Logged In: YES user_id=285591 Hi, I have exactly the same graphic card with a core 2 6600 and never saw your problem. Does it happens often ? Everytime ? any method to reproduce that ? About the fact of supporting dual core in jEdit, yes it does but I don't think it would change the performances a lot since your proc is already very fast. Anyway several tasks are made in separate threads ---------------------------------------------------------------------- Comment By: Marcelo Vanzin (vanza) Date: 2006-10-22 21:27 Message: Logged In: YES user_id=75113 Can you try to add this option do jEdit's command line: -Dsun.java2d.noddraw=true It might be that Java doesn't like with your video card driver... ---------------------------------------------------------------------- Comment By: LHEZ Gael (myshforum) Date: 2006-10-22 21:22 Message: Logged In: YES user_id=371121 Tested on my PC, with jdk1.5_06, and same problem. After giving a try on my other PC, no problem. I have a silly question, but jEdit support bi-core? yes? (I'm running it on a Core II Duo E6400, and the other PC is just a AMD XP2600+) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100588&aid=1581611&group_id=588 |
