Circa 6 months I observe Opera freezing. On my older computer I attributed it to its performance. Now on a new computer I've been using for 1 month Lenovo Thinkcentre neo 70t Intel i7, 16 Gb RAM, SSD it repeats.

At the time of freezing for 10-20 sec. the CPU is not busy, the RAM has plenty of free memory.

I've tried turning off HW acceleration, but no apparent improvement.

Opera support is not responding in any way, a tutorial to debug the problem would help
