i keep having this problem in photoshop: when i use the brush tool, either through the mouse or by tablet & stylus combo, no mattter what it doesnt do anything. But when i minimize my window and open it back again, i can suddenly see the changes to the image. only by doing this repeatedly can i see the changes i made to the document.
i tried resetting my preferences, but that made no difference. neither has restarting the application or computer.
does anyone know whats wrong? i cant do anything if i can watch my changes live 😭
Without any system info we can't tell you much, but I dare say that your hardware acceleration is completely not working/ messed up to the bones. Check the relevant preferences in PS, update your system's graphics driver. Anything more will require proper details.
