My Device is : Acer E5 476 G
OS : Windows 10 1809 (17763.316)
Graphics : Intel UHD 620 + Nvidia MX130
Driver : (Intel) DCH 22.214.171.12477
Your laptop has hybrid graphics (i.e. utilizes both Intel HD Graphics 620 + NVIDIA HD Graphics (GeForce MX130)). In this case, you should only be using the graphics drivers provided by Acer on their website. According to their website, the correct Intel HD Graphics driver version is 126.96.36.19908, not 188.8.131.5277. You must uninstall your Intel driver (and the NVIDIA driver as well if it is not the version on the Acer site) and install the version from Acer.
The reason why this is necessary is because hybrid graphics solutions require support for switching back and forth between the two solutions. This requires modifications to the drivers and Intel and NVIDIA do not implement these modifications, Acer does. When you installed the generic, unmodified driver from Intel, you lost support for switching (and you may have also lost support for other hardware features of the Acer design). The net result is what you are seeing. Switch back to the Acer-provided drivers to fix this issue. If you are unhappy with the state of the drivers from Acer, talk to Acer, not Intel.
Hope this helps,
