[SailfishDevel] app crashed when using Canvas in Dialog page
Hi,
I have Canvas in Silica Dialog page but app crashes when leaving dialog
page both with accept or cancel swipe. It does not crash always just quite
often.
the code:
Canvas {
id: imageCanvas
visible: isImageUrl
width: imgLoader.sourceSize.width
height: imgLoader.sourceSize.height
renderStrategy: Canvas.Immediate
onPaint: {
var ctx = getContext(2d)
ctx.drawImage(imgLoader, 0, 0)
}
}
Image {
id: imgLoader
visible: false
source: isImageUrl ? url :
}
The idea is to save image to the gallery in onAccepted if user has selected
that option as Canvas has save method which can be used to save image to a
file.
And it works fine, but causing app to crash sometimes when leaving Dialog
page with cancel swipe. SDK outputs a long crash dump.

Hi,
Sdk produces this dump, cannot really figure out the reason? Or what
backtrace you mean?

Do you have virtual keyboard visible when closing dialog?

Re: [SailfishDevel] app crashed when using Canvas in Dialog page
I tried FramebufferObject and now app crashes immediately when opening that
dialog page, right after Canvas's onPaint is executed (I have console.log
on last line of onPaint()).

ok.
I have not used renderStrategy at all in paint,
but renderTarget: Canvas.FramebufferObject
I have also dialogs there, and only way I got it broken, is that vkb case.
