macOS High Sierra version 10.13.4
Fabric Loader 0.4.8+build.159-1.14.4
Java Version: Java 8 Update 221
Minecraft Version 188.8.131.52
I installed replay mod with fabric and every time I hit render this happens (Image bellow, I don't know how to describe it).
Rendering the video is fine. It just has the box on the bottom left then the rest of the screen changes colour, as if it is the Minecraft sky in fast forward. A sound will play then on the bottom left box a text will appear, something like "rendering complete". If I then now resize the window and full screen it, the page would be back to normal, It will show the "open the videos" page in full view.
Resizing the window while the replay is rendering does nothing, only when the render is completed.
I also tried using replay mod without the mods above (except the required for fabric, fabric api, malilib). It still has the issue.
