@gitama2023 Are the display scales of Windows and browser both set to 100%?

I had the same problem a few hours ago, but when I set the display scale ratio of both my browser and Windows to 100%, the problem was resolved.

However, 100% display scale may not be suitable for users with high-resolution screens, or you may have other reasons for not wanting to set the Windows display scale to 100%. This could potentially solve your problem:

I tried keeping the scale of windows at my preferred 200%, while setting the browser's scale to 50% (multiplying still results in 100). This should also resolve the issue (if not, then revert back to 100%/100%).

Instead of adjusting the Windows display scale every time you use Sketch/Inpaint Sketch, I believe it is much easier to only adjust the browser's display scale.

Well, I tried change the zoom to 100%, and this bug won't appear again. Thanks.

PS: not only Windows, Ubuntu can also trigger this bug.

I'm sorry, I'm not sure how to solve this problem on Ubuntu.

You can still try adjusting the display scale of your OS and browser.

@cuffuuguu You don't need to sorry, the 'Change Browser Scale' is equally effective on Ubuntu.
