I haven't seen that crash here running from source, but if you've confirmed this fixes yours that's good enough for me. (Mine does crash running the 4.0.2 Briefcase package.)

It might depend on GPU drivers in your system vs my system (Windows 10). I confirm that on current master it crashes: test@xps MINGW64 ~/src/frescobaldi (master) $ py -m frescobaldi [8016:10048:0622/233500.750:ERROR:shared_image_factory.cc(880)] Could not find SharedImageBackingFactory with params: usage: Gles2Read|DisplayRead|DisplayWrite|Scanout, format: RGBA_8888, share_between_threads: 0, gmb_type: empty, debug_label: QWE_SharedImageBuffer [8016:10048:0622/233500.751:ERROR:native_skia_output_device.cpp(253)] CreateSharedImage failed.

For the records, in another computer (different graphic card) where I have a virtualized Windows 10, version 4.0.3 built by Briefcase runs just fine, no crash. Anyway, we'd better use these settings for all Windows installations to avoid potential crashes. In order to browse a simple documentation website we do not need GPU rendering, etc. I'll merge this tonight. |
