After upgrading to KDE Plasma 6.4, all applications running in the Wine environment, do not work. Some of them do not start, some of them start with a black window view, or start in such a way that you can't click anything in the application. The problem also occurs in some flatpack applications, such as Microsoft Edge. I only experience the problem when I have external monitors connected (usbc, MST). STEPS TO REPRODUCE 1. Update KDE Plasma from 6.3 to 6.4 2. Just run wine's apps OBSERVED RESULT I only experience the problem when I have external monitors connected (usbc, MST). When the laptop is disconnected from the external monitors, the problem does not occur.
