1973470 - [HDR/Linux] Deadlock on tab rearrangement

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect)

Description

[Martin Stránský [:stransky] (ni? me) (PTO, back on Jul 7)]

When we removed Shutdown() at Bug 1971968 we don't have tight control over layer shutdown which may lead to deadlock if WaylandSurface is used by widget compositor repeatedly.
