Again, the timer can be disabled in cases the framesvg is simpler, if it's really an issue (would like to have numbers tough)</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">It has a much simpler codebase and it doesn't touch framesvg in the library (and doesn't make things public)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">the important differences are two, that are imo 100% necessary to maintain a pixel perfect rendering (sacrificing that is a regression simply not acceptable in any case, even for non default themes, ever). At the same time avoids duplication of framesvg code in framesvgitem.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">potential issues:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
<em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;"> e037203748 support for tiling still need porting<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
</em> yes, it uses a qpainter, that means another copy: but again is necessary as framesvg knows how to render the end result pixel perfect, since for many themes the end piece is <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">not</em> the simple rendered element id.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
* yes, the final scaled texture is still uploaded as a whole, it only avoids to do it too often (like in animations) with event compression, again, only way to be sure it's correctly rendered all the time.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The latter two points can have the following optimizations:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Iff the frame does not have an overlay and does not have composeoverborders set, the following can be done:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
<em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;"> use Svg::image() to fetch the pixmap of the piece, since in that case would be valid<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
</em> resize the framesvg one single time, at a fixed size , like something > 256x256 (256 is not random thing, since we have 8 bits per channel, usually gradients will have no more than 256 stops) and disable the resize timer, this way we are even sure that only one image per prefix will be stored in cache</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I should add regarding the last two optimization points: i would like to see some real benchmarks about them, or i would not consider then necessary until then.</p></pre>
