[SOLVED]Screen flashes while gaming

When playing Dota 2, the screen flashes on and off constantly. When joining the game, it gives a no connection warning and joins late. I've missed the `join` part of the match sometimes.

In another game I have the following problem: when I switch to another workspace and come back to the game, the game is stuck

sudo journalctl -b | grep "nvidia":

Re: [SOLVED]Screen flashes while gaming

Known bugs with current versions of nvidia and wayland compositors (which one are you using, or is this a xorg session?). Fixes are underway, a large portion of it is in the current nvidia-beta driver, Plasma 6.1 which is in beta will also include the relevant explicit sync support.

If happen to use KDE, make sure you disable variable refresh support in the monitor settings, it's generally somewhat buggy, even more so on nvidia.

For a generally more stable experience currently and if you don't want to test beta drivers, test the xorg session.

All right, then. I'm using Hyprland, wayland

Re: [SOLVED]Screen flashes while gaming

I don't know if I need to start another thread, so I thought I'd ask here first. The problem might be the same. I get between 10-50 fps in CS2, it is very unstable, it can suddenly drop to 10, although people play at 200-300 fps, this is what I saw in the benchmark. I have a GTX 1050 Ti and 16 GB ram. Intel i5 9400F, 1920x1080 and SSD and medium graphics settings. I have the same problem in cs when changing workspace as in dota. But more than that, after 2-3 matches, the sound breaks in the game and then the game freezes.

Also, just to ask you, I understand that the fixes start in beta. We don't have Arch beta like Manjora, but if I switch to nvidia-beta, will I get the solution faster and will I be using the latest system?

Re: [SOLVED]Screen flashes while gaming

not sure about CS2, it sounds like you might be doing software rendering, but I suggest you open a new thread and post yourb vulkaninfo output to check whether you're using the correct renderer.

You'd get the relevant implementation from nvidia-beta yes, and that should already fix things for applications running in xwayland. Real proper support will also need to be added to hyprland, where I don't know what the status is.
