How do I know if my device's GPU (or graphics driver) is of subpar quality?

The other day I got a new tablet. It's an Insignia Flex 10.1 , a bargain Best Buy brand. A tablet's a tablet, though. Then I noticed, across several apps, this weird texture bleeding: (Click image to enlarge for better resolution) " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Notice the text. This didn't happen when playing this game on a different device. (Click image to enlarge for better resolution) " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Notice the dots. **Is this indicative of a cheap, crappy GPU or bad OpenGL drivers?** Or is it a coincidence and that the developers for these two apps use the same bad OpenGL techniques? And by cheap and crappy I mean *bad*, not just mediocre or underpowered.
