Clipping planes causing display glitches

Take a look at the video attached. When I add a clipping plane to the scene, in the perspective viewport, the name of the viewport will disappear. As soon as I delete the clipping plane everything works as expected.

Hi @jespizua

Thanks for reporting this and for submitting a video and a file. Unfortunately, I’m not able to reproduce this on my end with your file. The main difference between our systems is the version of macOS. I see you are running:

macOS version: Version 10.12.6 (Build 16G1036)

whereas I am on:


So I went ahead and test on macOS 10.12.6, but I still could not reproduce this. Frustrating. It looks like you are reliably able to reproduce it with any file.

Anyone else seeing this one?

Hi @dan, thanks for taking a look at this. I confirm this is still happening using 5.4 on both my machines, 10.12.6 and 10.11.6

It happens here when I move the clipping plane using Gumball, if I use regular move tool everything is normal. So, let’s make it clear:
1 Create a box in the perspective viewport
2 Create a Clipping Plane in the same perspective viewport
3 Activate Gumball and select the clipping plane
Each time I select the clipping plane having Gumball activated the name Perspective will disappear from the viewport, as soon as I deactivate the clipping plane everything come back to normal.

Can you reproduce it?

yeh I see this too, it happens in any viewport you have active with a clipping plane and gumball active, the viewport names disappear, when you deactivate the clipping plane they reappear, no biggie but something not quite right

Not sure why your first explanation didn’t work for me. Your second listing of steps allowed me to reproduce this one. Logged as RH-44807. Sometimes it takes “show” and “tell.” Thank you for being explicit.
