Weird diagonal artifact



I have update my graphic card GTX1070ti to RX6800. In the editor is a weird diagonal artifact vissible in my project. The diagonal is not visible with GTX1070ti. The diagonal is from left upper corner to right under corner, also when moving camera.
The project is build with VR Template 4.27.2. The same issue in the package.
The same when opening a blank VR Template.
Not vissible in NOT VR Template.
A problem with the RX6800 (driver) ?

Update unreal 4.27 to unreal 5 solved the problem
