Hi, all! It looks like there is a regression in Qt 5.12, specifically in Angle rendering backend. For some reason HLSL compiler searching code patch has been dropped between Qt 5.11.3 and Qt 5.12.0, so now it cannot find the compiler (MinGW 7.3 still suggests to use d3dcompiler_43.dll, while modern Windows 10 systems have d3dcompiler_47.dll only).
Here is the link to the patch that fixes the problem in Qt 5.12.0 branch: https://github.com/dimula73/qtbase/commit/e6e0d33e97704b8b63ecec41ffeb113fd9cdb7f9 The plain-text file is attached. PS: I haven't found the code for automatic application for the patches from src/angle/patches folder, so I just applied that manually and put the old patch into the folder. Please correct me if my understanding is wrong. -- Dmitry Kazakov
