I had to check the code again because I thought this was already working. Turns out the bug is in MainWindow::OnDebugDumpGeneric which is supposed to create the directory but accidentally hardcodes the shader path instead of using the variable. Can you update the PR?

i have updated the pr to implement the changes in MainWindow::OnDebugDumpGeneric

LatteTextureLoader_UpdateTextureSliceData now uses ActiveSettings::GetUserDataPath and OnDebugDumpGeneric properly creates the folder if it does not exist. tested locally this time...

While you're at it you might as well convert swprintf to fmt::format

I’m not planning to change the swprintf usage as part of this. you're free to open your own pull request.

at this point im not interested in attempting a fix, if someone smarter than me wants to tackle this, go for it.
