Magento white display and some time missing css when i clean cache and flush through terminal in ubu

[vipinsimpl4aed]

Please help me to find out the root cause of the white display or error page when I run the comment "$ php bin/magento setup:upgrade " after deployment of each plugin.

But it will be resolved when I run the comments

php bin/magento setup:di:compile

php bin/magento setup:static-contenteploy -f

I am using OS:ubuntu 16, Magento: 2.3.4

Hello @vipinsimpl4aed 

After setup upgrade and clear CSS/JS, you need to deploy static content, i.e., from pub/static for caching.

Run:

php bin/magento cache:clean OR php bin/magento cache:flush

If the issue still prevails, it may be related to permission.

I hope it helps.
