Hi Marius, We are using pure upstream Weston 10.0.2. Will open a gitlab issue.

No. I've tried this with 10.0.2 and 10.0.5 (our latest bug-fix release Weston 10). > > Or else can you please give some pointers to debug this issue? Are you using the upstream Weston version or something like the NXP fork? I'd suggesting opening a gitlab issue if this with Weston upstream. Possibly this might be a display driver issues if I can't observe it on i915. You could try disabling the animation entirely as a temporary work-around: Under [shell] section add startup-animation=none. > > Thanks, > Namit > > From: Pritama Biswas (QUIC) <quic_pritb...@quicinc.com> > Sent: Wednesday, July 3, 2024 6:29 PM > To: wayland-devel@lists.freedesktop.org > Cc: Namit Solanki (QUIC) <quic_nsola...@quicinc.com> > Subject: Blank screen observed when running Weston with pixman > renderer and drm-backend > > Hi Team, > > We are observing the following issue on Weston 10.0.2: > > When we launch Weston with drm-backend and pixman renderer, we are seeing > blank screen.
