problem with auto indent, qt creator bug?

[M_Qt]

i just installed qt 6.6.0 and qt creator 11.0.3 (community), i uninstalled my old qt and creator before installing this one.

but i have a problem with the automatic indenting feature. it's creating an alternating pattern for all my indents like this:

private:
  int var1; //2 spaces
    int var2; //4 spaces
  int var3; //2 spaces
    int var4; //4 spaces

my settings are:
Edit > Preferences > C++ > Clangformat settings:
Formatting mode: Indenting only.
Current settings: Qt [built-in]

these settings are supposed to create a consistent 4 space indent, and the preview window shows it working correctly, but in the ide itself it's broken and you get an alternating pattern.

if i disable formatting with Formatting mode: Disable. it does stop alternating the indents.

i tried deleting everything in %APPDATA%\QtProject to reset all the qt creator settings to defaults, but it didn't fix it.

so is this a bug or how can i fix this?

i think this is a bug so i just reported it on the jira. here is the bug track page for it:
https://bugreports.qt.io/browse/QTCREATORBUG-29841

if anyone else has this issue, i found a workaround to fix the problem, and it's listed on that page.
