[Panel-devel] QPixmapCache too small on large screens

[Hamish Rodda]

Hi,

I'm using plasma on a 2560x1600 screen and am finding plasma incredibly slow 
(2-3 seconds per update sometimes) and getting the following message:

plasma(15048) Plasma::Svg::Private::findInCache: pixmap cache is too small for 
inserting "/opt/kde4/share/apps/desktoptheme/default/widgets/wallpaper.svg_1600_2560" 
of size QSize(2560,1600)

Adding a hack calling QPixmapCache::setCacheLimit to 40mb fixed the problem 
(although probably 13mb would have been ok).  Perhaps the screen size should 
be taken into account when determining the size of the cache.

Cheers,
Hamish
