Anything that requires a screen redraw causes image to flicker white - setting path points, any painting tool. Dragging anything is particularly bad. If I have a visible selection, it will intermittently flash white. Clicking on the selection with the Marquee tool stops the marching ants animation, and the flashing, but as soon as I start dragging the selection, it flickers violently.
Turning off GPU acceleration makes the problem go away. I do not have this problem with the same driver in any other version of Photoshop. I do not wish to roll back to a previous version of the driver, as this one soled a number of issues I was having with previous ones.
I hopt this can be fixed soon.
I had the same problem as described here after having upgraded to PS CC 2019. Using win 10 64-bit, AMD Firepro W4300.
Solution: Update your AMD PRO/Firepro driver(s) and software, do that directly from the amd.com site. Installation: choose "clean" to remove all previous versions. Now all is fine agin re PS.
My PS preferences: Performance - Use Graphics Processor = Yes
My AMD driver setting: 10-bit color depth.
If your monitor allows and you're into photo/video post-processing, you really should use 10 bit color depth.
Hope this helps
Exact same problem here. Very annoying, and the constant bright, white flickering might possibly the triggering epileptic seizures out there.
My configuration: AMD Radeon Vega GPU running latest enterprise software, AMD Ryzen 7 1800X eight core CPU, 64GB RAM, 8K 10bit display, dual screen, Windows 10 64bit.
I do not know if this is still the case, or they have not updated this page.
Status as of Jan. 18/19, 2019
As mentioned above in the previous posts, I encountered the 2 problems in Photoshop (PS): strange colors in the UI and heavy flickering when using e.g. the clone stamp tool or the healing brush tool.
New updates are available:
AMD SW & driver update: 18.Q4.1, release date: Jan. 17, 2019
PS update of Jan 2019 related to urgent fixing of issues: released Dec. 19, 2018 (?).
My system before/when updating both: Win 10 Home 64-bit, version 1803; AMD SW/driver version: 18.Q3.1. GPU is an AMD FirePro W4300.
After the update of both, the AMD SW/driver and PS, I activated the usage of the GPU (Drawing Mode = Advanced) in PS including 30-bit display and 10-bit color depth in the AMD driver/SW.
Also, I updated the Win 10 version from 1803 to 1809.
Result: PS issues are resolved in both Win 10 versions.
However: I had to roll back the Win 10 update due to serious problems with my WiFi connection which became unstable and extremely slow – probably a driver problem.
Conclusion (in my case): PS issues are fixed with regard to AMD GPU, regardless of whether one uses Win 10 vers. 1803 or 1809. But I'm still running on Win 10 version 1803 due to other problems.
I hope this helps and would appreciate feedback.
