We have merged a GTK 4.0 Release Candidate (4.13.6) into pmaports which changes the default renderer. The new default renderer is a complete new implementation with clear benefits according to the developers. However, as any new big code changes, there might be some issues. If you experience any regressions, you can create a file containing GSK_RENDERER=gl under /etc/profile.d to switch back to the old renderer. In such case, it would be great if you open an issue to let us know.
