Hi, Jani!

It looks like Oliver has already submitted ii to gerrit. Should we do anything else?

Hi!

Thanks for this. Do you have a link to the patch which is in Qt 5.11.3 but not in 5.12.0?

Please write a bug report in Jira  and contribute your fix in gerrit (and directly in '5.12.1' branch), thanks

br,
Jani

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.
