Laggy Overlay in new Big Picture Mode on Linux

[Hunter99]

I tried the new Big Picture mode (-gamepadui) on my gaming computer which runs Manjaro (KDE Plasma 5.25.5) and in fullscreen mode it's laggy.

When I switch to window mode and resize the window to a quarter of my screen it runs smoothly.

Old Big Picture was also smooth in fullscreen mode.

I have the same issue on Windows 11, its basically unusable at the moment.

ok, from another thread, enabling GPU accelerated webviews fixed my issue and it runs great.

my Primary use-case is Steam Link, so it would be nice if this did Big Picture only on remote clients.

I tried the GPU acceleration too but it didn't fixed the lag problem on my linux machine.

For me on initial start window had tons of corruption, like where's shaders, but also it got really laggy after changing the UI scaling

With my GTX 1060 in FullHD Pig Picture ist laggy on any Linux. On Windows the performance is ok.
If I swap the graphics card for an RX 470, Big Picture mode runs smoothly in Linux.
I guess it depends on NVidia cards, AMD cards runs smoother. I also have similar problems with other gaming clients on Linux.
