I couldn't reproduce a crash with 50 consecutive open/cancel, so I'm thinking
this will be fixed in the next update then.

Re: [SailfishDevel] app crashed when using Canvas in Dialog page
Hi,
Complete app here
https://github.com/tace/jolla2gether.git
I created a branch "*canvas_crash*" for you. The canvas code is in
https://github.com/tace/jolla2gether/blob/canvas_crash/qml/components/ExternalLinkDialog.qml
.
To reproduce the problem.
1. Start app and select "Questions" from pull menu
2. Open any question page having picture. E.g. put to search criteria (from
pull menu) "summer" and you will see this question
https://together.jolla.com/question/44887/high-contrast-ambiences-summer-ready/
which has some pics.
3. Click a picture and you are on the Dialog page where the Canvas is.
4. Now swipe right i.e. cancel the dialog and then click the picture again
to enter Dialog page again. Repeat this until app crashes.

Re: [SailfishDevel] app crashed when using Canvas in Dialog page
Hi,
I'm hoping this will already be fixed in update 9 by the cleanup improvements I
did to the canvas implementation a few weeks ago, but just to be on the safe
side, I'd like to test it. Is there an example or app I could try to verify
that? (I'd prefer to get a complete example rather than recreating it based on
the posted code segment to ensure that it is covering the right cases)
cheers,
Gunnar

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()).

QEGLPlatformContext::makeCurrent: eglError: 3002, this: 0x71661d28

Re: [SailfishDevel] app crashed when using Canvas in Dialog page
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.

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.
