Launching MaxIDE pegs xorg CPU usage

| When I launch MaxIDE 1.3 - the version available for download separately from the forum here - xorg's CPU usage pegs to around 25% and remains there. This doesn't happen with any other applications I use on a regular basis, not even firefox or other IDEs. Before launching maxide:

| This might be related to how many files are / were open. If I open MaxIDE, and close any automatically opened files, the CPU remains at around 25% for xorg. If I then close MaxIDE and reopen it (therefore there are no files automatically loaded), xorg stays at about 1% CPU or less. It looks like perhaps something with the way that the text areas are drawn, and maybe that they are not cleaned up properly when the files are closed. Just a theory though. |

sounds for me really strange. what distribution are you using? version of xorg/xorg-server? does it happen to older versions of maxide? what arch are you using? 32bit or 64bit? if 64bit...are you using a chroot or a multilib system?

| I'm using Ubuntu 8.04 on a MacBook, 32bit 2.6.24-19-generic Not sure how to get the xorg version, but it should be the one that comes with Ubuntu 8.04 I didn't notice this before, but I can see if it happens with other versions, provided they launch... |

Well, this is weird, I just launched the original ide that came with the 1.30 ZIP file,

Retrying the new one downloaded from the forum still gives oddly high xorg CPU usage. System has been restarted a few times since I originally posted so it isn't a transient issue.

I'm not sure what changed in this version of the IDE but it clearly is doing something to make xorg freak out a bit. There is a different visual style / skin or something. It does look much nicer than the original IDE that came with 1.30... Not sure what else I can try. I pretty much can't use this as-is though, mainly because I don't trust it or like the potential effects of my machine never going idle. |

| My guess... new one : gcc 4.x old one : gcc 3.x ? (well, I thought Seb was using 4.x now, but I might be wrong :-) |
| ||
| I noticed similar behaviour but I haven't yet been able to track down what's eating the cycles. I am using gcc4.x to compile on my Ubuntu PC. If anyone has MaxGUI, and wants to see whether this is the problem, they can checkout and compile the latest versions of maxide.bmx and MaxGUI from their respective repositories, and let me know if they still experience high CPU cycles when running MaxIDE built from gcc3.x. |
