Perhaps the "freeze stuck" bug was "fixed" using new Nvidia driver 470

[Augusto7743]

I have used Retroarch in Linux for a few months and the more worst issue is when starting in full screen the program is totally stoped at point that not is possible move selection menus or use ALT+TAB for alternate to others programs.
That "freeze stuck" will continue for more than 1 minute and after is possible select menus and start a game , but when closing a game again will happen that issue.
I had always tested enabling or disabling several settings and not fix.
Today was updated the Nvidia driver for version 470.63.01 and not happen the issue above , but when enabling threaded video Retroarch will start and happen the "freeze stuck" for a delay of few miliseconds. Thus disabling threaded video not happen the "freeze stuck".

Have something wrong in threaded video code ?

To be clear, this isn't a generalized Nvidia Linux issue. I've never experienced it, and I'd have been seeing it for years were that the case. I did try enabling threaded video just now and just got the typical double reinit, but that's not abnormal at all. I'm afraid I don't know what to suggest for you, since I've never witnessed the problem in the first place.

Closest issues I've seen were an old driver bug related to vulkan on prime laptops (resolved finally in 460 I believe) and #10408.

Might be unrelated but the statistics don't show on threaded video either.

Using Linux Ubuntu nvidia driver 460 and Retroarch previous versions had that "freeze stuck" bug and with current version driver 460 and Retroarch current version not more "freeze stuck" , but disabling thread video start more fast and enabling have a little delay and in previous versions even disabling thread video had the "freeze stuck".
Search in the issue list you will see some users saying about that "freeze stuck" bug.
My topic here was to say a information thus if the bug return in next versions the information above is a clue to fix.

Hi,

I can't reproduce your issue I can enable threaded video and I have no freeze.

Can you be more precise how to to reproduce your issue step by step ?

1. Enable threaded video
2. Launch game ? Move in the menu ?

Moreover which DM are you using ? display server Xorg or Wayland ?

Which RA version are you using ? From which package ?

Thank you.

Tested in Linux Ubuntu 20.04 xorg and 21.04.3 xorg ... GT 640 drivers 465 and 470.

• Retroarch 1.9.9 and previous versions before 1.9.6 driver 465 in both Ubuntu 20.04 and 21.04.
  Starting Retroarch in full screen even without loaded content "freeze stuck" at point that also "frezze stuck" the OS for more than 1 minute and when closng content again happen "freeze stuck".
  Windowed mode not any problems.
  Any setting enabled or disabled not fix the issue.

• Retroarch 1.9.9 driver 470 in Ubuntu 21.04.
  Not more any terrible issues starting in full screen.
  The only strange detail is enabling video thread happen the "freeze stuck" for 500 miliseconds.

Search in users posts you will see users saying about "freeze stuck" happening in Retroarch for several previous versions that never was fixed.
