Hey there! This looks to be a duplicate of MC-101579, which was later marked as Invalid. The reason for this is because the problem that you are experiencing here, is caused by malware interfering with Minecraft. Please read the Moderator Note on the duplicated link for instructions on how to solve this problem. If this does not fix the issue, please contact Community Support, as the bug tracker does not have the appropriate resources to provide you with assistance.
Additionally, the bug tracker only handles issues relating with unmodified game versions and I can see from the screenshots that you've provided that you're using some kind of shaders. Since this can be reproduced in a vanilla environment, it's alright however, when posted issues in the future, make sure that they occur in vanilla.
