There still seems to be an issue with DirectX rendering with G-Sync. When using Nvidia G-Sync and DirectX, and when there is rendering taking place (cursor moving over a new button for example causing an animation), the app drops fps significantly. This can be fixed by setting the rendering mode to OPENGL or SOFTWARE but this isn't ideal. I assume this is a Skiko/Skia issue. This issue is also apparent in the Jetbrains Toolbox app which uses Compose for Desktop, I can fix the issue with changing the rendering mode as well.
