GNOME Bugzilla – Bug 615917
Scrolling is very slow on Mac OS X (10.6.3)
Last modified: 2010-10-17 19:24:02 UTC
I am using the latest GnuCash on Mac OS X Snow Leopard. I have a 4 year old Mac Mini - 1.66 Ghz Core Duo processor, 2G RAM. When I have only 100 elements in my GnuCash register, the scrolling is very slow. The painting gets very behind when either dragging the scrollbar control or using the scrolling on my mouse. It seems like the GTK quartz is not coalescing events when the application gets behind, so after I quit dragging the scrollbar or moving the scroll wheel on the mouse, the scrolling still continues. Normally Cocoa app, when using the NSView mechanism, will automatically get mouseDragged events coalesced. But if GTK is reading the event queue directly, it might need to do its own coalescing. I reported this problem in https://bugzilla.gnome.org/show_bug.cgi?id=615704 under GnuCash, but the developer thought this was a GTK quartz problem. Also, this developers fast Mac Pro does not exhibit the slowness I see with my older Mac.
I assume you have also run earlier versions of Mac OS X on this Mac Mini. Have you also seen this slow scrolling when running, e.g. Mac OS X Tiger, or has this problem appeared since you have upgraded to Snow Leopard?
I wasn't running GnuCash when I was using Tiger. Its only been a few months where I've been using GnuCash regularly, so when I was running Leopard (vs Snow Leopard now), I'm not sure I was using GnuCash yet. The other place I see mouse slowness is with selecting text inside of each field of a transaction in the GnuCash register, though this may be a different problem. 100 transactions in my GnuCash is a very small database.
I am marking this as a duplicate of bug 624025, since it is very likely the case that the cause is similar. *** This bug has been marked as a duplicate of bug 624025 ***
