I am currently preparing a first revision of patch for testing (not for committing). Patch will include the following: (1) Removal of path to handle application as being linked again 10.13 SDK (2) salvd.cxx: Refactoring/rework of AquaSalVirtualDevice::SetSize to use quad storage size for retina displays (3) salgdicommon.cxx: Refactoring/rework of AquaSalGraphics::SetVirDevGraphics to apply double scaling to virtual devices too (4) salgdicommon.cxx: Refactoring/rework of AquaSalGraphics::copyBits and AquaSalGraphics::copyArea to use a new unified method AquaSalGraphics:copyScaledArea to handle sources from scaled virtual devices as well (5) salbmp.cxx: Workaround for QuartzSalBitmap to downsample bitmaps from scaled layers (this workaround has still to be replaced by an implementation of scaled bitmaps) (6) Environment variable VCL_FORCE_WINDOW_SCALING to activate window scaling on non retina displays too (should look the same as without window scaling, but very useful for testing on a non retina display) Bitmap workaround causes blurry bitmap representations on retina displays as on non retina displays as well. This is desired for now, because implementation of scaling-aware bitmaps has still to be done. On retina displays it looks similar as on Mojave or Catalina. After patch has been tested especially according to unwanted side effects, following steps have to be done: (1) QuartzSalBitmap has to be extened to handle bitmaps from scaled sources, workaround has to be removed afterwards (2) Environment variable VCL_FORCE_WINDOW_SCALING has to be removed and replaced by a scaling of 2.0f on macOS (and by a scaling from the main display on IOS). After application, windows are able to be moved between retina and non retina displays without showing blurry text again. I will post a link to the patch here as soon as it is ready for testing.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
