Teams crashes when sharing entire screen and notebook connected to ultrawide monitor

[moniqa]

I'm currently running the Teams app 1.3.00.24755 (64 bit) running on Windows version 1909 and build 18363.1082. The notebook is connected to a 35“ Ultrawide Curved Monitor from LG..
Notebook display scale 125% and resolution 1920 x 1080
Ultrawide monitor scale 125% and resoluton 3440 x 1440

When I am on a call and share the entire screen of the notebook or of the ultrawide monitor, the teams app completely crashes.

Relevant errors in the log file:

@moniqa 

Please install the newest graphic drivers for your computer (check also the manufacturers page, e.g. if you have an HP you can use HP Support assistant), this looks like a driver problem.

@moniqa not sure whether this counts as necroposting, but for anyone like me who just had this problem today and is looking for a solution, I fixed it by turning off the HDR of the ultrawide monitor from Display Settings.
