Running Mint 20 on ThinkPad P15 Gen 1 with GPU installed. It took some time to get it working through GPU on Display Port (but I don't recall what I did). Was fine for ~about year, but recently I am having Telegram crashing when clicked on a picture or video. (Mysteriously, this happens only when displaying through DP with 4k resolution - 1080p is still working).

Other than that no other issues.
