@Maxnflaxl , by the way, if these files is subject to change after recompilation then maybe would be better to add them into git ignore or something like this?

No, the translation files are necessary and updated by cmake. We haven't found out yet why the <byte value="xd"> is added in some cases. @kogawulf experienced this too.

@Maxnflaxl , as I see it coused by lupdate: https://codereview.qt-project.org/c/qt/qttools/+/353347/25 So, maybe we have an outdated tool.

"On Windows, the line endings might be "\r\n", depending on the source file. In .ts files this leads to an extra tag <byte value="xd"/>. Fix this by converting Windows line endings to Unix line endings when handling string literals." (https://codereview.qt-project.org/c/qt/qttools/+/353347/25)

Seems not like we have an outdated tool, but incorrect line endings.
