Windows 10: Weird graphical glitches in browser and some apps

This happens only on my browser and some apps, not everywhere on the system. Why?

:)

 

Weird graphical glitches in area over video

I've been having a really weird graphical glitch recently - anything that's shown over video randomly becomes semi-transparent. For example, the YouTube search bar glitches between fully unreadable (mostly transparent) and regular. I'm on a laptop with
Intel HD Graphics 620 and the latest drivers and running the latest Windows update. Any reccomendations?

 

Crashing with weird graphical glitches

I have been having alot of problems lately and i don't know why, a lot of applications crash or get this weird graphical glitch. Here's a screenshot :

I have a GTX 660 with 8 GB DDR 4 RAM and an Intel Core i5-4570 CPU (3.20 GHz)

I recently updated my graphics drivers and this problem appeared. And i have no idea how to fix it, i have looked around everywhere and can't find something to reduce the chances of this happening or stopping it.

 

Weird graphical text editor glitch in a dual monitor setup on windows 10

My dearest superusers,

I have a very weird graphics 'glitch' for certain IDE's or editors, like TexStudio and Spyder. It happens that certain lines or words overlap with each other, and sometimes certain lines have different fontsizes even (not shown in next image)

Screenshot for one example of overlapping words:




It happens usually in my secondary monitor (LG Flatron E2350V), but if I remember correctly, it had appeared on my primary as well. My primary is just the one of my laptop (HP Pavilion - 14-al125nd). What I have noticed (from what I remember) is:

• When the problem appeared in Spyder in primary monitor, it was
  sometimes solved by saving the python file
  
• When the problem appeard in Spyder in secondary monitor, it was
  sometimes solved by maximizing the window.
  
• And at times none of the above methods worked for no monitor.
  
• When I drag one of the text environments (texStudio or Spyder) from monitor 1 to monitor 2, the text transitions into the glitched version.
  
• Also,some IDEs like Matlab, never experienced this problem. (And till now, I have never seen the problem elsewhere
  
• As far as I know, these two programs are the only ones where the glitch appeared.
  
• Lately, the problem does not appear in first monitor, but it still does in second one.
  

This suggests that the problem is time-varying and possibly also varies in its characteristcs.

To solve the problem, I've tried to:

• update to latests graphics drivers, both my integraded Intel card (HD
  Graphics 620), as well as my dedicated Nvdia GeFore 940MX card.
  
• Otherwise I've tried to search online but frankly, I do not really
  know the right search terms to find the same problem. Therefore I
  hope to find some answers or suggestions on this site!
  

Just to be clear, my question is what causes and/or what can potentially solve the problem?
Of course I do not know what information could be used/required to answer this question, so if there are any questions of additional details that I did not mention, please ask.

Sidenote: I am not sure whether my tags are correct either. Feedback is appreciated.
