GPU Screen Recorder has been released in version 6.1.4 on Flathub.

The tool records screen content using the GPU and works similarly to NVIDIA ShadowPlay on Windows, with support for X11 and Wayland on AMD, Intel and NVIDIA hardware.

The new version fixes a false error that sometimes made recordings fail and improves multi-GPU and COSMIC support.

Fix recording failing sometimes (false error). Improve multi gpu support. Improve cosmic support. Add option to only organize files if a game is captured.
