skate starts with weird resolution

For quite some time skate startet for me really weird. It changes resolution during the loading screens and when finally joined it looks like skate 1 / 480p or sth

The workaround for me is to go to graphic settings, change it from borderless fullscreen to fullscreen, accept changes, switch it back to borderless (because i had a hard-crash when playing fullscreen last time).

when exiting the settings it prompts me this

although i dont have unsaved changes. I click "yes" and can play like normal. Until the next restart of the game.
