Description

Hi everyone. System: 4.20.10-arch1-1-ARCH Faced with the Nouveau driver problem for the GT710 card. After loading to WM (swayWM), when opening the Firefox, the screen was immediately frosted and nothing was done. dmesg output itself: https://gist.github.com/nolik/1179a25a7a84f979aaca3d9b0badb08f

[ 99.818101] nouveau 0000:26:00.0: fifo: CHSW_ERROR 00000002 [ 99.818106] nouveau 0000:26:00.0: fifo: FB_FLUSH_TIMEOUT

According ArchWiki i try to add nouveau.noaccel=1 to kernel params => as a result WM stop freezing and able to use, but ALL LAGS and snowing on the screen. I try to disable GPU acceleration in Firefox, and run it => it's not work. Try to add QT_XCB_FORCE_SOFTWARE_OPENGL=1 to env variable and lunch Chromium => works to first button/action and freezing all.

Unfortunately, i have to use Nouveau coz swayWM doesn't support Nvidia drivers.
