Created attachment 142210 [details]

Interacting with a website in which a self-hosted potree.org visualisation is shown. I can reproduce it by zooming and panning around, it is not happening at a fixed location in the 3D space nor a specific interaction from what I can tell. Website was opened in Firefox, display hanged, then resumed.

-- system architecture: x86_64
-- kernel version: 4.18.14-arch1-1-ARCH
-- Linux distribution: Archlinux
-- Machine or mother board model: FUJITSU.LIFEBOOK S936
-- Display connector: 3 screens:
eDP1 connected primary 1280x720+1920+0
DP1-1 connected 1200x1920+3200+0 left
DP1-2 connected 1920x1080+0+0

The browser window was on DP1-2 every time I had this happen.

Comment 1 Denis 2018-10-26 10:31:53 UTC
hi, I am not sure that I am reproducing completely the same hang, but I got a crash (stable, right away after opening first example, Animation Path) of my desktop env, using mesa 18.2.1 (in your case, I guess, you have 18.2.2)

Could you please compile or download latest mesa (18.3.0) and check?

Because the same site (and it's models) can be opened normally on 18.3.0-devel (from Padoka PPA)
Comment 2 Denis 2019-01-31 14:46:19 UTC
Hey, did you try what I suggested? Is this issue still actual for you?
Comment 3 bugmenot 2019-02-06 12:35:31 UTC
I tried to reproduce it now, mesa is 18.3.2. I could not reproduce it.
