fullscreen video stops updating when using bgfx vulkan backend on linux #7820

Closed belegdol closed 2 years ago

belegdol commented 3 years ago

I have just noticed that at least 0.228 and 0.229 will stop updating fullscreen window after a second or so when using vulkan backend on Linux:

The music keeps playing and switching to window with alt-enter resumes the video updates. Switching back to fullscreen repeats the issue. With opengl backend everything works as expected. Is this a known problem? Is there any other info I can provide? Thanks.

This appears to be specific to nvidia drivers. My other machine running radeon via wayland is slow AF when in fullscreen but the image keeps updating.

belegdol commented 3 years ago

I tried to bisect this but I got as far back as 0.215 which is the oldest release I am able to get to compile and it also exhibits the problem. This would seem to indicate that the problem is with the enviroment change and not a mame change.

belegdol commented 3 years ago

This does not happen under wayland, only under x11. Which is convenient, because opengl does not work on wayland with nvidia binary drivers.

belegdol commented 3 years ago

https://github.com/mamedev/mame/pull/8469 does not fix this. It did not say it would, but it we could have been lucky.

belegdol commented 2 years ago

This seems fixed as of 510.47.03 nvidia driver. From 510.39.01 changelog [1]:

Worked around an issue that prevented some games from flipping (and therefore taking advantage of G-SYNC and G-SYNC Compatible monitors) on certain desktops such as GNOME.
