Some brushes in the graphics tablet feel oppressive, but some brushes draw a brush with a thin half and a thick back half. Have you ever encountered such a problem? Thank you for your suggestions ~

There are several possible reasons for your situation, you can check them one by one. 1. The tablet is not inserted correctly or has poor contact (reinsertion). 2. The tablet driver is not installed (uninstall and reload). 3. The computer conflicts with the tablet driver. 4. This software is not compatible with this tablet (please try other software). 5. There is something wrong with the pen of 5.graphics tablet (try it on other boards of the same model). 6. There is something wrong with the graphics card tablet (written test with other boards of the same model). 7. There is something wrong with the tablet cable (try to use another tablet cable of the same model). 8. There is something wrong with the computer interface (try another interface). 9. There is something wrong with the computer (generally this is unlikely, try another one). Basically, these are all possible causes. You just need to check them one by one. Personal advice, for reference only.
