Flicker with dithering enabled and specific image on the screen

Graphics / Linux Linux

Hello,

I’am getting annoying flicker with blender default GUI when dithering is enabled in the driver. Flicker is visible even if I take a screenshot of Blender window a display it as a static image on the screen with image viewer. If I turn off dithering for that specific monitor, flicker is gone. Strange thing is, that I can see it only on one if the monitors connected to the same card, others two are fine.

This is also new with 525 driver, I haven’t noticed such effect with older drivers.

I have an old GTX Titan X, the monitor affected is ZP Z24i and I have it connected through Display port. Other two monitors are connected by DVI and HDMI. Bug report and mentined image attached.

Now I have another monitor, Dell P2723D. I’am still getting flicker. It has something to do with Dithering controls. When I use 470 driver, is gets automatically 8 bpc depth and there is no flicker. With 525 driver it gets automatically 6 pbc depth and there is flicker. If I turn dithering off with 525 driver, flicker is gone, but image has banding.

Drivers 520/525 had a bug, should be fixed in 525.89.02

Thank you, I can confirm that. Got 525.89.02 driver from Launchpad and flicker is gone.
