The IMPEX 5.5.4 release
This patch-release fixes a GUI frontend freeze that sometimes appeared where it looked like the USBProtect station stopped working. We believed we had fixed it in 5.5.2 and 5.5.3 since we no longer could reproduce it then but eventually we could.
It turns out that the bug we were chasing was a GPU shader bug introduced in the new Mesa library we got with Sysctl Linux 42. Since our frontend does not do anything graphically intense we decided to disable GPU acceleration to avoid the buggy GPU shader.
USBProtect fix
- Turn off GPU acceleration in the frontend
