[2023] Does anyone know how to resolve these graphical issues? I got lines in all my interfaces (and the interfaces only), it happened after installing the last update. Drivers are up-to-date and so is the game and the Jagex Launcher.

Had a few similar reports to this - if you're being affected could you send over your tech specifications and I'll pass it on.

Update: if you could also supply your current driver versions will help us narrow it down along with your graphics settings

Spoke to the team - looks to be caused by nvidia anisotropic filtering, the teams still investigating solutions, but :
'For the time being players should just change anisotropic filtering in the nvidia control panel back to application controlled' this should hopefully resolve these issues.
