Ubuntu 18.04 / gtk3

With master toward 7.0, built with --enable-dbgutil, create a new Draw document, and insert an ellipde using toolbar -> crash. The console has this:

> warn:vcl.gdi:23344:23344:vcl/headless/svpgdi.cxx:133: unsupported SvpSalGraphics::blendAlphaBitmap case
> soffice.bin: /home/mike/lo/core/vcl/source/outdev/bitmap.cxx:689: void OutputDevice::DrawDeviceAlphaBitmap(const Bitmap&, const AlphaMask&, const Point&, const Size&, const Point&, const Size&): Assertion `!SkiaHelper::isVCLSkiaEnabled()' failed.

Comment 1 Luboš Luňák 2020-05-26 12:12:16 UTC

That doesn't make sense, according to the info you use Skia with gtk3, but that combination is blocked. Maybe you have explicitly forced Skia (there's an expert 'ForceSkia' setting)?

Comment 2 Mike Kaganski 2020-05-26 12:24:30 UTC

(In reply to Luboš Luňák from comment #1)

Yes you are correct - I must had enabled that at some point, and forgot. (But shouldn't the isVCLSkiaEnabled check return false in that case *if* it doesn't work there, even if forced? I don't know if it does, just asking.)
