<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">i agree with the analysis of the problem: the pixmapCache object is not always reset in ThemePrivate::setThemeName. there some issues with the implementation, however, that need to be addressed before it can be committed.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">this method's signature is leading to hard to read code and is going to be error prone. if we indeed move to a two-boolean method here, i'd prefer to see an enumeration used as flags in ThemePrivate. e.g.
enum { NoCache = 0, PixmapCache = 1, SvgElementsCache = 2 } CacheType;
Q_DECLARE_FLAGS(CacheTypes, CacheType)
void ThemePrivate::discardCache(CacheTyeps caches)
and then calls would become sth like:
discardCache(PixmapCache | SvgElementsCache)
this would reverse the meaning the the current booleans, but then the code becomes far easier to read as a result.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">it is unintuitive that a boolean called "keepPixmapCache" results in the pixmap cache being deleted.
a comment should be included here noting that deleting the pixmapCache object does not remove the on-disk backing.</pre>
