P: "Flickering" brush when painting in version 23.5

System details:

 

Surface Studio 2 i7

32 g of ram

GTX 1070

Windows 11 22H2

 

Since updating to version 23.5, I've noticed a couple things. There seems to habe been some kind of change to how brush input is being rendered. On the plus side, it appears to have slightly reduced latency, but there is also some kind of bug causing a flickering to happen as the tiles are drawn in. Its really strange, the flickering while drawing is accompanied by it sometimes taking a step "back" in its history, only for that step to reappear as I continue to draw. I tried disabling multithread compositing to see if that was causing the issue, but it didn't make a change. Also, the same flickering behavior is there whether drawing with the pen or the mouse, so it seems to be about rendering rather than the input method.

 

Just to be sure, I reinstalled 23.42 and the issue was gone. Then, I reinstalled 23.5 and it was back. 

 

Hoping this is solved in a patch soon, because I really like 23.5 and think with this bug solved, the experience / general input latency while drawing has potentially been improved. The bug seems specifically tied to rendering input, which is encouraging because any added fluidity is a good thing while painting in Photoshop. The problem may be driver releated to my Nvidia card, or the fact that I'm running the latest version of Windows 11, but it is definitely unique to 23.5 for me.

Just checked Deactivate Native Canvas and the flicker is gone, so I think you solved my problem... What does this option do? Is disabling native canvas a step forward or backward in rendering input? Don't I want native canvas for performance gains or am I confused?

Thank you for the quick help, that's really rad of you. I can't find that file anywhere, but when I saw your advice on the other thread, the first thing I did was reset my preferences. Would that have deleted the file? Where should I look for it?

So, now my question would be, for drawing performance / latency am I better off keeping version 23.4.2 and using Native Canvas and rulers until this bug is fixed, or using version 23.5 with Native Canvas deactivated and native rulers switched off?

If you can't find that file anywhere, don't worry about it.  You would have had to manually create and place it there.

 

Is the OS you're running an Insider Preview build of Win 11 22H2?

 

Would it be possible for you to attach or link to a video that shows the flickering problem?  

Does it happen with all brushes or one in particular?

Yeah, I think a long time ago I did that as a workaround for something but not for a while.

 

I'm in running the Release Preview version of 22h2. I've been running it for a couple months, also kept up to date on PS, no issues until this recent update. Short video of the flicker attached, thanks for your input.

Hey Chad, just noticed that I didn't aswer one of your questions... It happens with all brushes, from what I can tell, but is (possibly) more pronounced with the inky KW brushes that I use most.  The video I posted uses ExpressInk from the Spring 2022 pack.

Thank you!  The video is very helpful!  Looks like the canvas is flickering which indicates a GPU or compositing issue. If the problem goes away when you have Deactivate Native Canvas in Technically Preview preferences, it's a GPU issue. I'll have someone from that team take a look.

Hey Chad, sorry to bug you about this again, is the solution to this going to come from a small Photoshop update or a new Nvidia driver?

23.5.1 update today fixed the issue for me! No flicker, brush response / reduced latency is better than ever.

Ugh, sorry to retract 23.5.1 as a solution. Initially, there was no flicker but after switching to full screen mode at screen resolution (for me that is 4500 x 3000) the issue came back and then was there to stay. Had to revert back to 23.4.2 where it doesn't happen. Also, I have updated to the newest Nvidia Studio Driver which also doesn't seem to have solved the issue. Will keep an eye out for another PS update.

Checked today's update (24) with the new Nvidia Studio driver... Still get the same flicker unless I turn off Native Canvas. Damn, was really hoping today would be the fix.  Any idea when we can expect this bug to be patched?

Hi Micah,

We believe we have a fix for this issue in the 24.1 release, which is scheduled for mid-December.  The fix is also in the current beta build.  If you have a chance to install the beta build, please let us know if the issue is resolved. Thank you.

Hi Erin! I just ran the current beta and am very happy to report that the flicker is gone and the brush performance is *chef's kiss*. Absolutely awesome. Can't come soon enough, I've been literally checking every other day for an update. Really want to use this new version, stuck on 23.4.2 until its fixed. Is it my imagination that the brush input latency is much improved with whatever it is you are doing now? This adds a lot of value for people like me who primarily use PS to draw. Thank you!

Since the current Beta is so good (for me!) is there an easy way to import my preferences from my stable build and just use it?

Hi Micah,

I’m so glad to hear that the brush improvements are working for you.

There isn’t an automated way to transfer Photoshop Release settings to Photoshop Beta, but you can try copying files over from inside C:\Users\username\AppData\Roaming\Adobe\Adobe Photoshop 2022 to C:\Users\username\AppData\Roaming\Adobe\Adobe Photoshop (Beta)

Rename the files that are different. For example, the Adobe Photoshop 2022 Prefs.psp would be renamed Adobe Photoshop (Beta) Prefs.psp.  Also, please save a backup of your Adobe Photoshop 2022 Settings folder in case it’s needed.

Thanks!
