Have you updated Maya?

[jchen210149]

I am using Maya 2018 , but it works normal in other scene

[damaggio]

Understood but maya has updates...1 ,2  just wanna make sure u are up to date.

The last time people had this issue the solution was to lower the texture resoultion for the viewport.

I dont see any problems here, is that only happening with that billboard plack? try exporting and importing again. just that piece....is this file .mb?

[jchen210149]

its happening on all objects 

I tried lower viewport resolution to 1024 but same

export / import didnt work

file is .ma

I'll try update maya

thanks for helping

by the way I was thinking maybe I should download 2019 instead of 2020 ,because  there usually will be some bugs in the new released version ?

its works ,but error happened again later a while

it works if I do it again but dont last long

Yes, what's the rush, use 2019 for a while until they release the first 2020 update.

I don't know what else to suggest you for your glitch, im sorry, maybe someone else might chime in.
