I don't know why but, since I upgraded from 14.04 version to the newer 18.04, I have been experienced some weird behavior with dropdowns in both of my installed web browsers.
I'm using ubuntu 18.04, the gnome version, inside a virtual machine on vmware.
the virtual specs are:
- 20 GB ram
- Intel core i7-6700HQ octa-core, with all cores assigned to my virtual
- 8.0 GB of swap partition
- 35GB of HDD with 10GB free
- network over nat
the host specs are
- Windows 10 Pro 1803 with the lastest updates
- 32GB of RAM
- Intel core i7-6700HQ octa-core
- SO storage Unit: Samsung 960 NVMe ssd
- secondary (this is the one who has the vm hdd file) ST1000LM035
- Ethernet and Wifi are both ensambled by killer
since the hardware specs from the host are pretty decent, and this didn't happen when I was using 14.04, I think is worth to know if there is some kind of bug or is just a bad configuration on my SO due the upgrade.
this and a bit slow gnome transitions are the only things in what have I noticed a poor performance, most of the new SO is working like a charm, so, I don't think is an HDD issue either.
Note1: I had already disabled the hardware acceleration in both, chromium and firefox.
Note2: I updated the system via do-release-upgrade two weeks ago.
Note3: with eclipse, visual studio code, both browsers, tmux, 3 terminal windows, compiling in spring and angular, running sqldeveloper, postresql, msyql, pgadmin4, and a docker container with oracle10g, all runing at the same time, the SO had swaped like 200M, and this is the worst escenario I can have in my virtual machine, most of the time, the swap file is never used, so I don't think this problem is related to ram issues either.
thanks in advance.
