Description
I'm experiencing repeatable crashes on zooming in (too far?) of XYZTile display of Google Hybrid map as lowest level.
Here is a cut-and-paste of the crash report that would be sent to Apple: < https://pastebin.com/wcF63b1p >.
Note that the guilty thread is crashing on a call to QRasterPaintEngine::drawImage(QRectF const&, QImage const&, QRectF const&, QFlags<Qt::ImageConversionFlag>)
It is moderately easy for me to trigger this bug, so I may be able to provide more details from a different crash.

I have this too; see: https://issues.qgis.org/issues/19544. The crash is repeatable but not (for me) predictable. In my case I'm using Google Satellite rather than Hybrid.

Update: It appears I can avoid the crash as long as I don't zoom in beyond what looks like the tiles' native resolution (approx. 1:1500 scale at 2x magnification). Something to do with resampling, perhaps?

That seems to be (at least) consistent with my experience. Zooming in too far somewhat-repeatably triggers the crash.

does it happens only if the project contains xyz layers?

Yes, using an XYZ layer of the "Google Hybrid" (i.e. Air/satellite photos with roads overlain) is the only time I have observed this crash.

Please try on QGIS 3.4.1, if the issue is still valid change the affected version, thanks.
