Stamp tool on huawei

Hi, I’ m using Nomad on a matepad 11 downloaded through the appgallery, I didn’t get yet into too complex project but until now Is running fairly smooth.
I didn’t have any particolar issue at this point except with the stamp tool. Regardless of the default alpha pattern i pick and without thinkering the settings It Will only start to carve 2 or 3 Lines in the mesh. Trying the same tool on my android phone trial version seems to be working Just fine.
Am i missing something or It May Be something with this release for appgallery?
Thank you

After restarting seems to be working fine
