From 604a86895feb6639417fe957dfc95191f7f63565 Mon Sep 17 00:00:00 2001 From: Dongwon Kim Date: Wed, 28 Sep 2022 14:58:05 -0700 Subject: ui/gtk-egl: egl context needs to be unbound in the end of gd_egl_switch A thread often fails to bind an egl context to itself after guest VM is rebooted because the context is still owned by another thread. It is not very clear what condition makes this happen but this can be prevented by unbinding the context from the thread in the end of gd_egl_switch.
