** Description changed:

  A fresh Xubuntu 18.04.1 install (from an ISO), on a machine with only the 
Intel integrated graphics  (i9-9900k => UHD-630). The graphic drivers module 
seems to be properly loaded, but X rendering seems to fallback to LLVMpipe.
- This was the case immediately after the install. The performance of the SW 
rendering improved after the first update with the latest packages but it is 
still very problematic, for ex. Eclipse has very severe flashing glitches as it 
redraws the editor windows.
+ This was the case immediately after the install. The performance of the SW 
rendering improved significantly after the first update with the latest 
packages.

  I tried using the latest stable mesa from ubuntu-x-swat/updates but it
  did not help (I ppa-purge'd it before generating the bug report)
