this is my first post. I just purchased a Dell notebook that I use with elementary os Loki 0.4 and I have two problems: 1 - When I use the Chrome browser and Firefox (both updated) I have problems with the graphics card (Intel Corporation Broadwell-U Integrated Graphics (rev 09) or Flash (not activated) have not yet understood. The image can be seen flickering in the bars of the instruments of application and browser content. The problem It presents only with browsers.
2 - The Logitech Mouse M171 http://www.logitech.com/it-it/product/m171-wireless-mouse?crid=7 It has a strange behavior; is too sensitive and often does the scrooling alone and mouse settings in elementary os does not give me a chance to fix the problem.
Thanks to those who can help me and I apologize to my English Googled.
