[kicad-users] Re: pcbnew is amazing slow under windows 7 - workaround
This is not really a Kicad bug. The problem I believe is with Windows 7 Aero themes. Try changing your desktop theme to classic theme. You should see the difference. A lot of applications are having issue with the Aero themes because they mess with the display API. --- In kicad-users@yahoogroups.com, Stephen Eaton sea...@... wrote: Thankyou This was causing me much frustration as a first time user of Kicad on a test project over the last few days, while I can put up with a few of kicads lacking features this was going to be a killer for me (I must admit I love Kicad, coming from eagle). It's now acceptable using this as a work around. Has it been logged as a bug? Regards, Stephen..

The interf_u.brd took many seconds to display or refresh. We can see the lines draw one by one. I tried different binary versions, with the same problem (KiCad-2010-03-14-SVN2456, KiCad-2009-02-16-final, kicad-20080825). Like you I tried on virtual machines: XP and Linux 64. And here, despite of virtualization overhead, the same test is responding instantly (so for me this is at least 50 times faster!)! After this I found a very simple turnaround solution: go with explorer to pcbnew.exe, click properties, and check unactivate desktop composition under the compatibility tab. With this the speed becomes from unusable to acceptable, but not as smart as under the linux or XP VM. So this acts as a conflict with the new display system of vista/win7. Hoping this little information might help you and other people that will face this problem.

By this way refreshing rate is in my opinion 10 times faster. Does someone noticed the same issue?
