Does anyone know why the OpenGL sizing calls have no effect on Linux? These include glScale(), glTranslate(), glOrtho(), and glViewport(). We did build QT 5.5.1 from source, using the default build process and parameters: ./configure, make, make install. Are there extra build parameters to get sizing capability? Perhaps including parameters for OpenGL hardware acceleration? Thanks.
Hi and welcome to devnet,
Can you give a sample code that shows that behaviour ?
What Linux distribution are you using ?
What is your graphic stack ?
Also note that Qt 5.5.1 is pretty outdated, you should consider to move to a more recent version. Qt 5.9.2 is the latest LTS.
