Sometimes, when I restore a minimised window it will be entirely rendered as multi-colored static, until I minimise and restore the window again.
This seems to happen most reliably with my VPN app, but I've also seen it happen with everything from Firefox to VLC and GIMP. When it happens with Anki it sometimes only happens partially, which I don't think I've seen for any other program. Here is a screenshot of the pattern:
As it's easy enough to clear up the static this doesn't impact me particularly, but does it suggest that my GPU may be failing? I'm using a NVIDIA GeForce GTX 460 which has been trucking along for about a decade now, but other than this I haven't seen any graphical issues.
I am using the âNVIDIA driver metapackage from nvidia-driver-390â and this has occurred across at least Ubuntu 21.10 and 20.04, possibly earlier.

คนส่วนใหญ่ไม่เข้าใจว่าการถามคำถามมากมายจะปลดล็อกการเรียนรู้และปรับปรุงความสัมพันธ์ระหว่างบุคคล ตัวอย่างเช่น ในการศึกษาของ Alison แม้ว่าผู้คนจะจำได้อย่างแม่นยำว่ามีคำถามกี่ข้อที่ถูกถามในการสนทนา แต่พวกเขาไม่เข้าใจความเชื่อมโยงระหว่างคำถามและความชอบ จากการศึกษาทั้ง 4 เรื่องที่ผู้เข้าร่วมมีส่วนร่วมในการสนทนาด้วยตนเองหรืออ่านบันทึกการสนทนาของผู้อื่น ผู้คนมักไม่ตระหนักว่าการถามคำถามจะมีอิทธิพลหรือมีอิทธิพลต่อระดับมิตรภาพระหว่างผู้สนทนา
