weird preview generating problem here and in the main repo

[abozahran]

When i click generate it takes some time and nothing show on preview window but in the cmd it say generating done and when i check outpot folder i can see the generated photo
when i press generate for the second time it take some time less than the first time as normal but i can see now the generated image is the first one showing in preview window not the scond image , when i check outpot folder i can see the second generated image which not showing yet in previw window unless i click generate for the third time , it keep going like that
