Git commit ec10bca7db2a53001fead8ab1302455da06ef985 by Arjen Hiemstra. Committed on 10/11/2020 at 13:49. Pushed by ahiemstra into branch 'master'. Fix rendering borders the proper size with software fallback Apparently using qpainter strokes results in unpredictable behaviour so do the same thing we do in the shaders and first render a rectangle at full size with border color, then a smaller one with fill color.

Created attachment 132285 [details] Above: ShadowedRectangle with 1px thick border. Below: Qt Quick Rectangle with 1px thick border SUMMARY STEPS TO REPRODUCE 1. run a program that uses ShadowedRectangle with `QMLSCENE_DEVICE=softwarecontext` OBSERVED RESULT - Corners are pixellated - sides are faint - bottom and right side are 2px thick EXPECTED RESULT - corners and sides should have the same smoothness, thickness and position as Qt Quick Rectangle SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20201007 KDE Plasma Version: 5.20.80 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1 Kernel Version: 5.8.4-1-default OS Type: 64-bit Processors: 4 × Intel® Core™ i7-6500U CPU @ 2.50GHz Memory: 7.6 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 520
