Photoshop 27.8: WinTab bug still causes freezes when both brush panels are visible
Reference to the previous thread:
After Wacom Support officially confirmed to me that this bug could be reproduced in Photoshop and had already been reported to Adobe, I would like to open a new bug report referring to the previous report, which was subsequently converted into a question.
At the same time, I found a workaround that allows affected users to continue working with current Photoshop versions, Wacom tablets and WinTab instead of Windows Ink.
Why WinTab is important to me
Using WinTab with Wacom tablets eliminates a number of serious usability problems that I experience with Windows Ink.
These include, among other things:
- lagging or jerky sliders
- difficult input in numerical fields
- intermittent loss of pen pressure, especially when switching between applications
- additional input problems in Adobe applications and partly at Windows system level
These problems do not occur for me when using WinTab. From discussions in the Wacom and Adobe forums, I know that many other users have similar experiences. This is why maintaining reliable WinTab support remains very important.
Bug description
The problem has existed since Photoshop 27.4. It definitely did not occur in Photoshop 27.3.1.
When WinTab is enabled via the Adobe workaround and the brush-size slider in the Brush Settings panel is adjusted, Photoshop freezes.
Switching repeatedly between Photoshop and the Windows desktop can sometimes make Photoshop respond again temporarily. The document can then usually be saved and Photoshop closed, but normal editing is no longer possible. As soon as the brush-size slider is used again, the program freezes once more.
Wacom Support has confirmed to me in writing that this behaviour is known, can be reproduced and still occurs in Photoshop 27.8.
Additional finding and workaround
I have now found that the freeze occurs when both of the following panels are visible at the same time:
- Brushes
- Brush Settings
Both panels contain a control for the brush size. When the brush size is changed in one panel, the corresponding value apparently also has to be updated in the other panel.
As long as only one of these two panels is visible, Photoshop works normally for me. When both panels are visible at the same time, Photoshop freezes after several brush strokes or brush-size adjustments.
Workaround
Place the Brushes and Brush Settings panels in the same panel group as separate tabs, so that only one of them is visible at a time.
This allows me to continue using Photoshop 27.8 with Wacom and WinTab without the freeze.
However, this is still only a workaround. It is particularly inconvenient for users working with two monitors specifically so that important panels can remain permanently visible and immediately accessible.
Based on the behaviour, the problem appears to be related to the synchronization of the brush-size controls in the two panels when WinTab is active. This is only an observation from my tests; the exact technical cause would of course need to be determined by Adobe.
Request
Please keep this thread categorized as a bug report.
The problem is reproducible, has been confirmed by Wacom Support and has existed since Photoshop 27.4. It would be greatly appreciated if Adobe could investigate and fix it so that reliable operation with WinTab and Wacom tablets remains supported.
This is particularly important because Wacom tablets are officially supported and widely used by professional Photoshop users.
