Hi, as the title states the High DPI Scaling does not work anymore after the latest update.
Can confirm, broken at 4K here, was working fine before the update.
I hope they fix this soon. My launcher is barely usable without that setting.
I filed a bug report about it a few days ago, checked it today and it was attached it to a defect, so it looks like they’re aware of the issue at least.
I believe I am having the same issue because Checked or Unchecked the High Dpi Scaling does nothing in game and the text is just too small.
(Solved I believe) I changed my resolution from my custom resolution to the standard 1920 x 1080 selection and I found I could scale the UI to 150% instead of just 125% and that helped significantly.
