Hi there. I tried different distros, mostly interested by Ubuntu and Zorin OS (ubuntu based), but a problem is driving me crazy on all distros. Around the curson you can see that corrupted square (I found a lot of people having glitches on that area in different ways), but recording tool can't see it.
I use an old laptop with an i5 sandy bridge with an iGPU and an AMD HD7000, and I would even try to disable the AMD gpu to try with the igpu or the reverse if that may help.
I'm a completely new entry here so please talk to me in a very dirty way, and any hint would be appreciated.
Thank you.
