Firefox 85 is very broken on my system. I suspect NVIDIA. I have to disable webrender (gfx.webrender.all), otherwise Firefox completely locks up / is unusable. Webrender was working in 84 and previous releases. avindra goolcharan On Mon, Feb 1, 2021 at 1:51 PM Winfried Bartnick <winni@bartnick.info> wrote:

Hi!

FireFox bug under rare circumstances:

* Look a TV Channel with FF

* Dont switch the channel for 70..80 minutes.

After 70..80 minutes the broadcast beginns to stutter and sometimes looses the connection.

The CPU percentage is on heavy load the little applet in the taskbar shows.

And the rest of the desktop works like molasses .

This is the very high time to close FF. The FF process needs 10..15 seconds to leave the RAM.

If you dont stop FF at this point you first will recognize that the mouse stops to work.

If you are lucky you can switch with Alt-CtrlF1..F6 to a konsole and kill (-9) FF.

Otherwise there is no reaction anymore from the whole machine and you have to do a hardware reset.

This is reproduceble and I had this situation for 4 times until I recognized to restart FF every hour.

My Hardware: AMD Ryzen 5 2400 G, 4/8 cores, 16 GB RAM,

Suse Tumbleweed.
