Created attachment 144415 [details] screenshot showing the preview with blurred images SUMMARY The screenshots of applications shown in the preview of grid based task switched are blurred. I understand these are just suggestive images, but since they are blurred and look like have artefacts from bad scaling, they give the impression that a low quality jpg is used. it would be good to have more clear images. STEPS TO REPRODUCE 1. Go to system settings and search for task switcher. 2. Choose grid dropdown from the list of task switcher in the resulting page 3. Click on the image icon to see the preview of grid task switcher I am attaching a screenshot of the preview.
