Short description of error
Strange grid pattern appears on the compositor background when zooming in (when backdrop is on).

This is what it should looks like:

This is what it actually looks like:

And this only happens when I zoom in. At a very far-away view the background gradually becomes normal:

This does not happen on my other devices, so I think it might be a hardware compatibility problem. Also, I had the latest graphic driver installed and the graphic card supports OpenGL 4.6:

Exact steps for others to reproduce the error

Open blender
Switch to the compositor workspace,
Enable backdrop
zoom in.

Hi, thanks for the report. I am not reproduce on master: 05ab3356a719ca1991dc993e2a055962e24aa138 and 2.93.5

Are you able to recreate the issue with factory settings: {nav File > Defaults > Load Factory Settings} ?

Yes, the same thing happens after loading the factory settings.

Some additional info that might be related:
Blender occasionally freezes on this device when the 3D viewport is in the preview mode. Blender itself is still working, I can save files or do operations with keyboard shortcuts, but the window stops refreshing, and becomes black when it is resized. I can't stably reproduce this, but it consistently happens when I work with blender.

I had the latest graphic driver installed

Hi, sorry for the late response. Probably you have checked for the update from device manager.

Checking from device manager will always say: Best driver for your device are already installed.
Please try to update it from here: https://www.intel.com/content/www/us/en/support/products/80939/graphics.html

(As this seems to be a driver related issue so updating will probably fix it)

No, the driver is up to date according to the website. Also, this does not happen in Blender 2.91.2 on the same device, so I'm not sure if the problem is in the graphics driver or in blender.

Does this happen with any of the other node editors?

No, the shader editor and the geometry node editor don't have this problem.

Update:
This problem still exists in the blender 3.0.1 release and on the Win11 platform.
However, this doesn't happen in Linux (Ubuntu21.10, Gnome, Wayland session) on the same device.

This might be a driver issue, since in the environment where this problem happens, Blender also freezes periodically when in 3DView preview mode.

Is it the same glitch seen on #92890?
If they are the same, I think we can merge this report into the other (since the other has steps that can be replicated on any GPU).

No, I don't think they are the same. In my case, everything works fine (selecting, moving nodes) except the pattern in the background. Also, I noticed just now that this problem only appears when the backdrop is turned on.

Hi, is this still replicable with newer intel drivers (31.0.101.2111)?: https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html

Yes, I have updated my intel driver and it still happens
