Comment 7 for bug 1849787

Also just want to note: it feels like since the Dock is showing in fullscreen (it isn't really fullscreen). There is a huge amount of CPU usage + input lag. Switching back to 19.04 was like night and day. OpenGL 64-bit game runs fast and good on old release.

On new one- 19.10 the dock is not possible to hide and it doesn't feel like true fullscreen (huge input lag with 144 Hz monitor).

(Apologies if this is in the wrong place to report bugs pertaining to dock showing in full in other applications - OpenGL games etc), it's my first bug report.
