Hi Everyone,It was recently recommended to me that I enable DMA2D on my project to possibly alleviate another problem that I'm having detailed here (Weird horizontal artifacts in touchGFX buttons - STMicroelectronics Community). My question is, how d...

Hi Folks and Happy New Year!I've been trying to track down a problem I'm having with my project for several months now. Essentially I'm getting these red-ish lines through portions of my buttons, but only when (I presume) they are drawn or redrawn - ...

Two additional observations:1. The character distortion appears to go away when I shrink the font down to about 60 (currently its at 80)2. If I set the option 'Use DMA2D Accelerator (Chrom-Art)' within the touchGFX settings in MX to 'No' but leave ev...

On additional thing I just noticed - if I set the button's alpha value to 254 or less, instead of 255, I don't seem to get the artifacts. I don't know how this factors into the problem, but figured I would mention it.

@Eiffel - came across your post yesterday when I was trying to solve the same, or a very similar problem. I realize you've probably found a solution by now or otherwise moved on to other things, but just in case it is helpful to you or someone else. ...
