Short description of error
Blender freezes on vertex paint on linked mesh data.

Exact steps for others to reproduce the error

In default scene duplicate linked (Alt+D) default cube.
Try to enter vertex paint mode.

p.s. On original cube you can enter, but painting doesn't work.
p.s.s. Sometimes blender crashes.

Note: I cannot reproduce in Debug builds, for me, this only happens in Release builds

Not sure it is the same issue as I gt a different stacktrace; but when vertex painting on both objects introduces a threading issue on release builds. To reproduce in debug builds you have to comment out the drw_mesh_batch_cache_check_available function.

Apparently this started with bf34b0c8f4

@Jeroen-Bakker, will assign to you then.

Workaround added for 2.90. I keep this ticket open to research a better solution or to make the workaround permanent.

It seems that the sync can be done with GPU_finish() instead of BLI_task_graph_work_and_wait(task_graph) or drw_mesh_batch_cache_check_available(task_graph, me).

(I can't reproduce the vertex paint bug if I replace drw_mesh_batch_cache_check_available(task_graph, me) with GPU_finish() in debug build whereas I have the bug without any sync)

In my armatures test file, on windows, i78700k it brings the framerate from 39/40 to 48/49 fps playing the timeline:
