We’ve been noticing an increase in screen redraw glitches, specifically in InDesign, since the last few updates to CC. While they’re pretty cool (if you like random distortions) and can produce effects like the above, they’re actually a sign of bigger issues and something you should check out.
The glitches are caused by compatibility issues with the GPU Performance function which Adobe started introducing to Creative Cloud applications In around 2014. The idea was to enhance performance by enabling applications to access the GPU processor on video cards, thereby boosting screen redraw, animation and video. You may have noticed when Photoshop started to do that dizzying animated zoom effect.
The problem is, not all GPU chips are compatible or supported. This can present as interesting and intriguing screen redraw glitches, such as the ones illustrated here, but can have more serious effects such as random quits and crashes, documents appearing in black and white, jagged artwork and pop up error messages about “GPU Performance Features are not available”.
The immediate solution is to turn off GPU support by clicking the GPU icon
or by selecting GPU Performance in the application preferences. Turning GPU Performance off should solve the issues right away though you may also notice a slowdown in application performance.
You can then try Adobe’s suggested troubleshooting steps to see if you can restore the GPU functionality.
We’d be interested to know if you’ve had any issues related to GPU performance and how you solved them, so get in touch in any of the usual ways.by
