    5.4.0-215-generic #235-Ubuntu My problem has somehow fixed itself over night. Sadly, I cannot say what I did. There was no additional computer restart or anything like that, the computer just ran from last evening 18:00 (where the problem still persisted) to now (13:45, where the problem is somehow fixed). Still, thanks SGaist for trying to help.

    Hmmm very odd! I closed and re-opened VS and now it works as expected - though black selection on a black background is VERY hard to see.

    @Christian-Ehrlicher said in Qt Creator: cmake errors after downgrade of MSVC compiler: 17.9 should also work. Make sure to start with a clean build dir and also no CMakeLists.txt.user in the source tree I did everything, but forgot about .txt.user Will try that... EDIT: However, after the torturous downgrade/upgrade experience, my VS debugger decided to behave, so I'll keep you advice for the future.

    @Iann29 Hi, I know this is a little late and I was running into the same issue but this is what fixed to for me. I went into the kit menu and I a kit for Desktp Qt 6.9.1 MinGW 64-bit (default) that had always come up as an unsupported/unavailable kit. However, all I had to do was clone it in the kit menu, see here. [image: 468b3f2d-cea4-4c50-bf91-0600151c6c1b.png] Then when I created a new project with Qt Quick Application for Python with PySide6, it let me select not only the python kit but also my desktop one that allows the designer to work.

    @Shap QPlainTextEdit will (should) behave the same as QTextEdit so far as sizing is concerned. They are both for multiline input, and can grow vertically. QLineEdit is for single-line input, and would not grow vertically. Same as the other widgets you talked about.

    I finally managed to get proper help back again, so I'm sharing the solution juuuust in case some other lost soul comes here in search of an answer. Clone the QtCreator source code. Checkout version v7.0.2 (this is the last version that supports Qt5). Build it against Qt5. Select "QtWebEngine" as the help renderer. Not only did rolling back to v7.0.2 + Qt5 give me proper help, but it also fixed a whole plethora of other annoying bugs. And even if there was any actual functionality added since that version, I didn't notice it, so I didn't even lose anything. [image: 681d75c2-ecb0-4a7a-8680-f0fa0267bf36.png]

    @AlGig Newer versions of Qt may not support the old Android versions and hardware. The Android version in my phone is 14. It may not make a lot of sense to work with Android 6.
