Videos Illustrating Screen Redraw Artifacts with Open CL On

Permanently deleted user
Here are three short videos captured while using Capture One Pro 6.1. The videos should be self explanatory. The screen redraw artifacts disappear when Open CL is set to Never.

Hardware: Intel i7-870 (Lynnfield), 8GB DDR3 memory, AMD 5770 with 1GB memory
Software: Windows 7 Ultimate 64-bit, AMD/ATI Driver 10.12.

1. Screen redraw artifacts caused by auto-adjustment (Ctrl+L).


2. Screen redraw artifacts caused by manual adjustments (exposure, contrast, etc.).


3. Screen redraw artifacts caused by switching and resizing images.

    OK, this to me visualizes the problem clearly. We will try to fix this shortly.

    We are trying to reproduce the error.

    Can you test changing the exposure using the same image where you first set Clarity to zero?

    Certainly. Here's one starting with a brand new variant created by copying the sample image with the Clarity tool set to 0. The redraw artifacts start to appear when the Clarify tool moves beyond 1.

    OK. This is what we found also.

    Expect this to be fixed in next software update (soon).

    Paul,

    Thank you for the update. The redraw artifacts problem is fixed. The sample videos illustrating the problems have been removed.

    It looks like the artifacts are back. 6.3.3 version, dual monitors setup. Artifacts appear during any adjustments - contrast, exposure etc. As soon as OpenCL is switched off everything gets ok.

    I noticed a number of similar problems with OpenCL set as "AUTO" and when turned off everything was fine. 🙄
    I have ATI FirePro V4900 that is NOT on supported list. ☚ī¸
