Hi there! Thanks for reaching out about your brush issue in Sketch Pro. I see you’ve set your brush opacity to 100 and the color isn’t white, but the brushes still aren’t working as expected. Let’s figure this out together.

To start, can you tell me if the brushes are not painting anything at all, or if they are just very faint or behaving oddly? Also, are you working on a specific layer, and is that layer's opacity also set to 100%? Sometimes if the layer opacity is low or the layer is locked, brush strokes won't appear properly.

Meanwhile, here are a few quick things to check and try:

1. Layer settings: Make sure the layer you’re painting on is not locked and that its opacity is also at 100%. Sometimes layer opacity affects brush visibility.

2. Brush mode: Confirm that your brush mode is set to "Normal" rather than any other blending mode like "Multiply" or "Screen" which can make strokes look transparent.

3. Brush settings: Check in your brush settings panel if there are any controls like opacity jitter or flow jitter—these can affect stroke opacity dynamically. Set them to 0% if applicable.

4. Size and flow: Verify the brush size is sufficient to be visible, and flow is set to maximum if available.

5. Reset brush: If your brush has been customized, try resetting it to default to rule out configuration issues.

6. Zoom level: Make sure your zoom is not too far out, as very tiny brush strokes can be hard to see.

If after these checks the brushes still aren't working, let me know what you see, and we can dive deeper.

Are you comfortable trying these steps? If yes, please update me on the outcomes, and we’ll proceed accordingly!

still not working:(

Thanks for letting me know it's still not working. Since the basic settings are correct and the brush is still not functioning, let’s try a few deeper troubleshooting steps to get to the root of the problem.

1. Restart Sketch Pro: Sometimes, software hiccups may temporarily affect functionality. Please close Sketch Pro completely and launch it again.

2. Update Sketch Pro: Confirm that your Sketch Pro is up to date. Using an outdated version may lead to bugs. You can usually check for updates within the app under Help > Check for Updates.

3. Graphics Driver: Since you’re using Windows 10 with a WebKit device, there may be compatibility issues with your graphics drivers. Please check that your PC’s graphics drivers are current. You can do this through the Device Manager under Display Adapters or by visiting your GPU manufacturer’s website.

4. Try resetting the preferences: Sometimes configuration files become corrupted. Resetting preferences to their default can help:
- Close Sketch Pro,
- Hold down Shift + Ctrl while launching the app to reset settings.

5. Create a New Sketch: Try opening a fresh canvas or creating a new sketch to see if the brush works there. If it does, the problem might be with the specific file you were working on.

6. Run as Administrator: Right-click the Sketch Pro icon and select “Run as administrator” to ensure there are no permission issues blocking brush functionality.

7. Reinstall Sketch Pro: If none of the above resolve the issue, consider uninstalling Sketch Pro and reinstalling it to fix corrupted program files.

If these steps don’t fix the brush problem, it would be good to review any error messages or behavior details you notice when trying to paint. Let me know how these go, and I’m here to guide you through the next steps.

In the meantime, I found a helpful resource for troubleshooting Sketch Pro on Windows2.

Are you okay with trying these?

I am using a tablet

Thanks for sharing that you’re using a tablet. That’s an important detail! Could you tell me which type of tablet you’re using? For example, is it a Windows tablet, an iPad, or another type? Also, are you using a stylus or your finger to draw?

Usually, on tablets, brush issues can be related to pressure sensitivity, stylus drivers, or app permissions, especially with Windows tablets or devices needing specific drivers.

Here’s what we can check next given you’re on a Windows tablet with Sketch Pro:

1. Stylus or Tablet Driver: Ensure your tablet’s stylus drivers are installed and updated. Without these, your brush input might not register correctly.

2. Pressure Sensitivity Settings: Open Sketch Pro’s brush settings and verify if pressure sensitivity is enabled or if something is disabled that could affect brush behavior.

3. Tablet Input Mode: Some tablets have different input modes (pen, touch, mouse). Make sure the mode is correctly set to pen/stylus.

4. Permissions: Check that Sketch Pro has permission to access pen input in Windows 10 settings.

5. Try Using Finger or Mouse: Just to test if the brush works with other input methods, try drawing with your finger or a mouse.

6. Windows Ink Settings: If your tablet supports Windows Ink, make sure it’s enabled as Sketch Pro might rely on it for proper pen input.

If you can provide which tablet model and stylus you’re using, I can give you more tailored instructions. Let me know!

where is pressure sensitivity

Great question! In Sketch Pro, you can find the pressure sensitivity settings by going to the menu bar and selecting Edit > Stylus Responsiveness. This is where you can adjust how your stylus pressure affects brush opacity, size, and other dynamics. Tweaking these settings can help your brush respond better to your pen pressure on your tablet.

If you want, I can guide you through the steps:
1. Open Sketch Pro.
2. Click on the Edit menu at the top.
3. Choose Stylus Responsiveness from the dropdown.
4. Adjust the curves and sensitivity sliders to your liking.

This should help with enabling and fine-tuning pressure sensitivity on your device. If pressure sensitivity is still not responding, make sure that Windows Ink is enabled on your tablet since Sketch Pro relies on it for pen input.

it's taking a long time to load...

Thanks for sharing that the loading is taking a long time on your tablet with Sketch Pro. Let's try to pinpoint what's causing the delay and fix it.

Here are some practical steps to improve Sketch Pro’s load time, especially on a Windows tablet:

1. Close Background Apps: Tablets often have limited resources. Make sure to close other apps running in the background to free up memory and CPU power.

2. Check File Size: Large or complex Sketch files with many layers or high-resolution content can slow loading times. Try opening a smaller or new Sketch file to see if the problem persists.

3. Clear Autosave or Cache Files: Sketch Pro can accumulate autosave or cache files that may slow startup. If possible, clear out temporary Sketch files or autosave folders.

4. Update Sketch Pro: Running the latest app version can improve performance and fix known bugs. You can check for updates in the app or on the official Sketch Pro website.

5. Tablet Performance Settings: On your Windows tablet, check the power settings and set the device to high-performance mode rather than battery saver or balanced, which can restrict resources.

6. Restart Your Tablet: A fresh restart clears memory and background tasks—the oldest trick but often effective.

7. Graphics Driver Update: Make sure your tablet's graphics driver is up to date, as outdated drivers can cause slow graphics processing.

8. Reinstall Sketch Pro: If loading remains slow, reinstalling Sketch Pro may clear corrupted files causing delays.

If you’re working with very large files regularly, I’d recommend breaking files into smaller parts if possible to improve performance.
